Body Energy Usage

I ponder macro-nutrition needs a whole bunch. Here’s what I have handy, though my technical references are scattered and omitted.

There’s always a need for roughage, vitamins, and minerals, which come from foods with very low calories/kilojoules. Aside from that, the three main macros have specific needs.

A body needs 125 grams of carbs for your brain/nerves; just under 1 gram of protein per kilo of lean body mass to maintain tissues/muscles; and around 30g of fat for cellular and neurological structures. This is usually around 1200 kcal per day, but varies by person 10-20 percent.

Anything else you eat is either poop, or gets converted to sugar. Sugar is burned if it’s needed immediately for exercise (growing, standing, walking, cardio, whatever, anything other than sleeping). Any sugar that is not immediately needed is stored in muscles as glycogen, up to around 4% of your muscle mass. All sugar past that is turned into fat and stored in our fat cells.

This is where “whole grains” comes into play. If it’s not ground up, it takes longer to break it down. However, if you take grains, and mill them into a powder, IT IS NOT WHOLE GRAINS. Just because there is fiber in the food does not mean it’s slow to absorb. The less processed the food, the longer time period over which it trickles energy into your body. If it’s super processed, it all absorbs very quickly, and your body may have trouble figuring out what to do with it unless you’re depleted already.

This is also where some insulin resistance comes from, and why diabetics have normal sugar metabolism in their muscles during exercise, even if they are short on insulin, or are resistant to it. Resistance is GLUT4 which causes glucose receptors to move to the cell membrane, but exercise does the same thing – muscle is hungry, it asks for more. Muscle is not hungry, it asks for less, even if you try to overfeed it. Where would it put this excess sugar? It can only store so much.

During exercise, your fat cells can liberate about 90% of your weight in pounds as usable calories per hour. For me, it’s about 260 calories. The gap is made up from glycogen in the muscles, which is good for just about 90 minutes. If you exercise hard, and stop at 60, and rest for 30, those 30 mins still use up that glycogen for delayed processes, cleanup, etc.

Eating carbs cannot provide as much energy as glycogen, but it’s the next best thing. Also, if you’re fasting, your glycogen reserves get burned up pretty quickly. Glycogen is 3:1 water to sugar, so this is why the first week of dieting is so awesome. No, that’s not fat. It’s muscle energy.

Any energy deficiency not covered by food will be covered by muscle damage. About the same number of calories can be broken down out of injured muscle cells. For me, this is a total of muscle and fat sourced calories of about 520 calories per hour. If I exercise for 3 hours with no food, then my power output drops to 130 watts, which is about 520 calories per hour.

The best option to limit muscle damage, limit recovery time, and optimize exercise benefits when going for more than your glycoge, is to eat as much every hour as you burn, minus the calories that can come from fat. Staying carb focussed can give more energy, and can be easier to absorb, though for some people, this slows the breakdown of body fat.

Staying fat focussed keeps the fat burn mechanisms running, but it takes twice as much oxygen, which means you’re hear-rate limited. It’s less about muscle conditioning then, and more about cardiovascular improvement.

Staying protein focussed is tougher on the kidneys. The aminos have to be converted for use as fuel, and that’s a lot of extra ammonia to pee out. That can be an issue when dehydration might already be at play.


Cycling Fuel

Max bodyfat you can burn in an hour is roughly 1 gram per 10 pounds, or in calories, 9 times your weight in pounds.

Anything else is food, muscle glycogen, or actual muscle tissue. Glycogen max is about 4% lean muscle mass, which usually is enough for 90 mins, plus or minus. Food is whatever is in your gut, though exercise slows digestion.

Bonk is when you have used up all food, and your glycogen stores, effectively exercising while fasted.

Bonk power is the max sustained energy ouput when you are fasted/bonked. This is fat burn, and muscle breakdown, combines.

Average watts is roughly 1/4 your calories per hour.

Me as an example
I’m 280 pounds, and bonk power for me is 133 watts, which is about 520 calories per hour. Doing that pretty much guarantees cramps from muscle breakdown.

Biking, I tend to burn 750-850 calories per hour, but I can peak at over 1000 in some instances (beginning, well fed, well rested, very driven).

That’s a big gap, because being big, I get more wind drag, which is 50% of your energy above 15mph. I also take more energy to climb a hill.

Downhill is faster, so less benefit (less time spent going downhill), and often waste the energy by riding brakes so as to not plow through others.

I do best consuming 600 calories per hour while riding more than 90 mins.

So, I have to eat the equivalent of a meal every hour to keep up, and reduce cramp risks. Most of that needs to be carbs that break down in less than an hour. Also, I don’t want to have a bathroom break every hour.

Ride Fuel
Sugary colas have phosphate, glucose, and fructose – all good for refueling. Cookies, sandwiches, etc usually are low roughage, good energy density, and include salt. M&Ms were actually designed to be endurance fuel for the army, and they hold up pretty well in a plastic bag.

Basically, all the things that are bad for you normally make great endurance fuel.

As to proper “race fuel”, honestly, it’s too low calorie for someone my size. Some people only need 200 calories an hour to stay fueled, so half banana, a 2″ square of granola, and a swig of gatorade is fine. For me, that would be a whole bunch bananas, and two quarts of gatorade. Just too much bulk.

Impediments
Add to all that the need for oxygen to build ATP (actual muscle energy chemical). It takes 35% more oxygen to burn blood glucose than intra-muscular glycogen. Fat takes twice as much oxygen as glucose. High heat, humidity, low pressure, altitude, carbonation, and alcohol all reduce oxygen availability. Transport of glucose into the cell takes ATP. Digestion of food takes ATP.

Diabetes, Insulin Resistance, and Metabolic Syndrome
The key there is to not eat much carbohydrate outside of the exercise times. When glycogen reserves are full (muscles recovered), and adipose cells are replete, then why would you need more fuel? That’s the practical wording of the physiology here, despite the perception of a faulty hunger mechanism for the obese, or lack of islets for type I, or the defective signalling in Type II without obesity triggers.

Exercise induced glucose uptake is normal in diabetic muscle cells:

Exercise may increase glucose sensitivity:
https://www.ncbi.nlm.nih.gov/pubmed/3899806

While glycogen is being replenished, glucose uptake by muscles in normal. GLUT4 is transported to the membrane during exercise, even in absence of insulin.

Bicycle cross-chaining

Mark loves to prod me about cross-chaining, because it’s formally a naughty-no-no. I thought I’d give some observations, since I am a chronic cross-chainer.

Cross chaining wears the sides of the sprockets, which is never what wears out. I ride like I am a 1×9 unless I’m on hills. No problems. All major makers support 1×11 (single gear in front, all the way back and forth in the rear).

Cross chaining puts a side load on chain pins, so use a chain whose plates don’t pop off. Most are made by KMC, with a brand label on them. I found SRAM branded chains hold up better. SRAM was the first to offer 1×11 drivetrains. KMC branded, Shimano branded, etc would pop a link by 600 miles. Maybe better now, but I have no reason to change brands. Bell chains are just too heavy/slow/frictiony, but work fine. Whippermsn chains are super durable, but expensive. Chains with a dimple or flat pin edge are better than the ones that look like a wite cutter went after them.

Wear on the teeth, ramps, and pins of the cassette/chainrings is due to shifting. Side loads don’t matter much, but heavy loads do. Don’t shift under high load, and they will last longer. If you hear a crunch when shifting because you waited to downshift, that’s more damaging.

Wear on chains is mostly from higher wattage, incorrect lubrication, and grit abrasion. Clean and lube your chain any time you can hear it at all. Try different lubes and see what you like. You can even throw it in a jug of 50wt motor oil, or molten candle wax if you like, but make sure to wipe it off well. Oil only needs to be inside the rollers. Anywhere else attracts grit.

Wattage, well, whatever power you can put into a chain is part of the fun, but if you are 285 pounds like me, and stand to power up a hill, expect more wear.

Lastly, when your chain gets to 0.5% stretched, replace it. Letting it go longer causes additional wear on the sprockets.

The only other issue to bring up is practical, not wear related, and that’s dropped chains.

If you are all the way tiny in the back, and shift up to the big ring in the front, expect to drop the chain off the outside, onto the crank arm.

If you are all the way small in the back, and try to shift to the small ring up front, expect to drop your chain between the cranks and the frame.

If you are fast, you can soft pedal, shift 2-3x in the rear, then shift up front, before losing much momentum. Chain guards and idler arms are not super effective at preventing drops caused by cross chaining.


Bicycle Tire Pressure

Optimal tire size and pressure isn’t always known. Here is a great calculator I use when I set up bikes.

The “Bike + Rider” weight is usually about 10% over your out-of-the-shower weight, and includes your clothes, tool bag, bottles, bike, etc.

The middle calculator automatically shows front and rear tires separately. I recommend that.

For tire sizes, you can pick what you have installed, and see what’s the best pressure for front and rear.

I like to run 2 different sized tires so I can keep the same pressure front and back, but due to frame limits, my rear tire is still too narrow.

If ideal for a road bike is under 80psi, (light riders), then you might consider going with a thinner tire. You’ll find it easier to spin up.

If ideal is over 120psi, you might consider a wider tire, because higher pressures can be harder on rims, tire casings, etc.

If you’re riding dirt, then lower pressures are better, to a point. Under 30psi usually means rock crawling, low speeds, and a tubeless setup. Over 80psi usually means you’ll have traction issues on softer surfaces.

Also. this person’s domain is “Dorky Pants R US”, which is just really great fun.

Gym Workout Routines

I was talking with a friend about my Gym routine, I thought I’d share some of that here. It’s kind of a wall of text, soI tried to organize it for easy skimming.

I keep a notepad on my phone to track what I did and what’s next. End of workout, I add the updated list to MyFitnessPal in the exercise notes. This keeps me from twiddling my thumbs during rests.

#### Warmup is cardio:
* About 10 mins or 200 calories warmup on the recumbent bike. I’ll start at about 50%, and crank it up to 100% a couple of times. I try to vary my RPM, but tend to hang out around 70. I have long legs, so momentum is a factor. I make sure I clear 160bpm, but I never get to max HR. Sometimes I try to draw pictures with the hill profile.

#### Safety warmup for exercises I’m not sure about:
* 10-20 reps at 50-60% just to make sure everything moves right, especially for heavier weight exercises.

#### I usually go for strength
* Target is 2-4 sets of 6-10 reps per exercise.
* If I make it to 16 reps, I bump up the weight on the next set.
* Sometimes I’ll do 8 reps, then drop 40% and do another 8.
* If anything pinches or doesn’t feel right, I’ll back off the weight.
* Not so worried about cardio since I average 75 miles per week on a road bike.

#### I do circuits for time efficiency:
* Whole Body Days: alternate upper/lower, front/back, with 30 second rests between circuits.
* Upper OR Lower Only: I’ll do 2-3 exercises with a 60-90 second rests.
* I average almost one working set for every 2 minutes. That includes the set, equipment setup, walking between machines, updating my notes, and any rest/cooldown time. That excludes the warmup time at the start. (eg, a 2 hour workout has 20 mins of warmup, and 40-45 working sets. A 1-hour workout will have 10 mins warmup, and 18-24 sets.)

#### With a workout buddy:
We could alternate on the same machine with 60-90 second rests. This is less overall workouts, but more social. We could also do the circuits, and just be one machine off from each other. Less social, but more efficient.

#### Workout Duration:
I prefer a longer, whole body workout every 4 days. I get better results, and less wasted time. My goal is to grow muscle mass, and I’m missing the sprinter gene, so recovery time is usually 3-5 days instead of 2-3 days for most people.

If I have only 1 hour, it’s best if I stick to only upper or only lower, because exercises always pull in a other muscles a little. I don’t feel I get quite as good of a workout this way.

#### Upper Body Exercises:
* Freeweight bench row (Low-Back sparing vs seated)
* Chest Press (like a bench press)
* Lat Pulldowns
* Seated dips (because I’m too heavy to do real dips yet)
* Chest fly & rear deltoid fly (same machine, diff settings)
* Biceps curls (cable or dumbell)
* Triceps extension (Slow to improve)
* Sometimes I do a shoulder press or a vertical row, but those are not so great on my shoulder sockets.
* Lateral dumbell arm raises.

#### Lower Body Exercises
* Freeweight seated calf extension (Soleus Muscle)
* Rotary Calf Extension (Gastroc Muscle)
* Inner/Outer thigh (adductor/abductor)
* Leg Curls (Hamstrings)
* Leg Extension (outer and inner quads, nearer the knee)
* Leg Press (because it doesn’t load my low-spine like squats & deadlifts do.)

###### Back Pain avoidance (Chronic and Acute)
* Nothing with a torso twist (wood choppers, obliques) – always causes days of increased pain.
* No abdominal crunches – Still hurting from 2 weeks ago when I let my form get sloppy.
* No back extensions – Same as with crunches, though a 45 degree bodyweight back extension bench would be fine if I could find that at my gym.
* Backed off of seated rows, just to be safe. I’ve moved to bench rows, though bent-over single-arm dumbell rows are okay too (off-arm is on the bench, so no low-back load).
* I should be doing planks and leg lifts at home, but I keep forgetting. This gets core without abusing low-spine.
* I should do more stretching on non-workout days, but I keep forgetting. This helps keep from putting too much strain on low-back when moving around.

#### Preferred Machines
I like the Hoist machines my Gym has best, but I’ve maxed out the leg press. Not sure I want to use the freeweight leg press without a big spotter. I like most of the Precor machines, and use them for things missing from the Hoist line-up. Last are the Life Fitness for a couple things, but they use bigger weight stacks for the same effort, and just seem to be on a different scale from all of the others.


Calories

This is what SEEMS to make the most sense for me. No *way* is easy, but this seems the least hard.

Energy Plans:

  • Defer first meal until actually hungry (9:30a-12:30p for me)
  • Keep each meal before 3:30pm around 12% of my daily intake.
  • Eat before I get ravenous (around every 2 hours).
  • Try to keep a reserve of about 25% of my calories for the evening.
  • Don’t be TOO aggressive (20% deficit is okay, but 40% is not).

Procedures:

  • Keep extra servings away from my plate/bowl.
  • Split up snack/mini-meals when I’m not hungry.
  • Stay busy (yay computer!)
  • You have to exercise, because your body will reduce your BMR to keep from losing fat reserves.
  • Hungries are worse the day AFTER exercise, so save your calories for tomorrow.

Foods:

  • Lots of broths, leaves, fresh veggies to add bulk, and fill in when I’m STILL HUNGRY!
  • Make sure I get the food groups and vitamins daily / weekly rather than every meal.
  • UMAMI: Your tongue creates Peptide YY it detects meat, glutamate, etc. Reduces hunger by 30% in the lab.
  • VITAMIN A: Hunger hormones are produced by fat cells. Empty fat cells do not get recycled without Vitamin A.
  • VITAMIN D: Vitamin D is blocked by Vitamin A, and is deficient for many indorsy people.
  • CALCIUM: Requires Vitamin D to be absorbed. Prevents brittle bones.

Some days will be better than others. Don’t give up. Keep tinkering.


Italian Cream Cake

Sharon ran across a recipe that looks amazing. It is very similar to my mom’s recipe, except they use melted butter in place of the oil+butter_flavoring; and they use twice as much icing.

Italian Cream Cheese Cake Recipe

Ingredients
1/2 cup butter, softened
1/2 cup shortening…
2 cups sugar
5 eggs, separated
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1 cup buttermilk
1-1/2 cups flaked coconut
1 cup chopped pecans

CREAM CHEESE FROSTING:

2 packages (one 8 ounces, one 3 ounces) cream cheese, softened
3/4 cup butter, softened
6 cups confectioners’ sugar
1-1/2 teaspoons vanilla extract

Directions
In a large bowl, cream the butter, shortening and sugar until light and fluffy. Beat in egg yolks and vanilla. Combine flour and baking soda; add to creamed mixture alternately with buttermilk. Beat just until combined. Stir in coconut and pecans.

In a small bowl, beat egg whites until stiff peaks form. Fold a fourth of the egg whites into batter, then fold in remaining whites. Pour into three greased and floured 9-in. round baking pans.

Bake at 350° for 20-25 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.

In a large bowl, beat cream cheese and butter until smooth. Beat in confectioners’ sugar and vanilla until fluffy. Stir in pecans. Spread frosting between layers and over top and sides of cake. Store in the refrigerator.


For reference, Here is my mom’s recipe, slightly annotated by me. She kept it on a 3×5 card in her recipe box, but it might have been something she got from her mom.

Mom’s Italian Cream Cake Recipe

Let set up overnight in the fridge.

Note: Individual slices freeze very well and are extremely tasty while still frozen.


Disable Strava Live Segments on Garmin

Garmin support says to disable individual segments on your device. Well, new segments show up still, and things get re-enabled. When Segments are enabled, it chews up more battery, just like following a course. Also, Garmin support takes DAYS to respond, and seems to send you to a level zero support queue first.

Strava support was awesome. I got a simple, exact response in three hours. To disable live segments, go to garmin connect. From the hamburger menu in the top left, click the arrow next to segments (way down in the list). Click the button to add it to your dashboard. Now, you’ll see the widget on your dashboard. From there, click the gear on the widget. Choose “Use Garmin Segments”. BLAM! You’re back to not using Strava Live Segments. You can toggle it on and off there, even though the initial enablement is on Strava’s webpage.

I wanted this disabled, because every time I would go near a segment, it would beep at me a few times. If I crossed over the start of a segment, it would beep no less than 15 times before it gave up. This is from an Edge 520 on version 7 code. Maybe it’ll be better in the future, but it’s just a distraction to me. YMMV

Spinal Health

My critical stretches are:

  • Calf stretch just because it reduces referred pain on hamstring stretches, and because I tore a gastroc once.
  • Hammies get a hurdler stretch or similar. Tight hammies are big, bad back things, and a major problem for me.
  • IT bands get a figure-four, or a leg over stretch to help reduce piriformis syndrome.

Others I enjoy when remembered:

  • Pidgeon pose gets adductors AND IT bands a little, because I cannot really do the splits. This is mostly for 2 days after a long bike ride.
  • Quad stretch, usually just grab my foot behind me and get as much stretch as I can. This is more for my knees than anything.

Core strength I need more of:

  • Planks in all 4 directions also help core. Front plank can be replaced with pushups if form is good. Modified planks/pushups as necessary to prevent strain.
  • Rows, whether off a doorframe, or a table, or with proper equipment, are important. However, a year post-op, and I’m still not really comfortable with twisting under load. I do one arm at a time, and keep my shoulders square. YMMV.
  • Walking / hiking are great for core if it’s more than a few minutes, and more than just on a track or treadmill.

Aerobic/Calorie Burn

  • Road bikes are low impact, but the bending is not always best.
  • Spin bikes are easy to sit upright and get comfy, while burning calories, but the class matters a bunch.
  • Some people run, but if your heel hits the ground, it just hammers your spine.
  • Swimming, if that’s your thing. More of an upper-body thing.
  • NOTE: Stretching after a good warm-up will be much more effective. Also, a good warm-up will break down some of the tight strands the same as stretching, just smaller amounts per step/stroke/whatever. Also, if I don’t stretch after a long bike ride, everything goes bad faster.

Other Stuff

  • There are other body stretches I should do, but I don’t suffer when I don’t do them. The /r/bodyweightfiness has good enough reference that I mostly ditched all of the other lists, charts, and PT printouts for it. http://www.reddit.com/r/bodyweightfitness/wiki/kb/recommended_routine.compact
  • Aspirin for NSAID since my family has a history of clots, and Ibuprofen/Naproxen increase clot risks when used long-term.
  • Hot Tubs/showers are awesome for relaxing muscles, preventing cramps, etc.
  • Extra salt when I exercise, because I’m a salty guy. Seriously. I cramp up if I don’t get enough, and this could be 1-2 grams of salt per liter of water consumed, depending on the temperature outside.

are we mental

The question is not “how do I get out of the rut, overcome depression, or solve my self esteem issues?”
The question is really, “Am I willing to love myself even if I cannot?”
(ps, The answer is yes. Pick yes!)


Tasty!

Butternut squash with coconut butter and cinnamon. Best food ever. TYVM slavetrunks, I mean Erica!

Unfortunately, I’m apparently developing a mild allergy to coconut. I have a very slight case of pharyngitis from sleep deprivation, and the pureed coconut texture is the same pattern of sensation as the sparkles I feel since having consumed it with supper.

I better back off, because I love coconut. Don’t want to ruin grated, chunk, and candied coconut just for this magical elixer I’ve survived without until now.

HEATMAPS!

I updated my GPS heatmap on Strava. They only do for Cycling OR Running, but nothing else, nor a combined map. *sigh*

So, my walks that had GPS were converted to runs. Some had a little running. It zooms way out, because most of it was in the Bahamas, but there’s a little blob on the trail behind my house. I also have non-GPS chunks at a couple campsites, and in Argyle, but they’re not on any maps.

Anyway, here they are:

Sanger Chase Ride

Ride to Sanger with the Sharon group. I was 22 mins late leaving the house, so I told them not to delay the start time. They waited 5-6 mins for me at Hwy 377 and Bonnie Brae. It was a hard push to catch up, and Sharon pushed hard once I got in sight.

Unfortunately, this sort of punished/burned out some of the others as well, especially Jim F. Jim tried to hang on, but at the end he finally admitted he needed to work his way up to this length of ride. He completed it, but with our waiting, it was 2-3 hours extra. That being said, for being about 3 months post-op for hip replacement, he’s doing awesome.

Becky took the SAG wagon back from lunch because of other committments.  Karl took it because he broke a drive-side spoke in the middle where it’d been notched by the chain about 2000 miles ago.

Men’s Ride

Karl, Jim and I went for a quick spin. Pretty muggy out there, but the temps were nice. We started early, and rolled about 7:05am from the AMC pond, and about 6:50 from my back gate. Ended up a little further than we planned, but was good. Wind was brutal. This was a pretty hard push to only get 16.2mph. Average watts shows the truth.

I stayed near the front for much of the second half of the ride, but I was never far ahead. It’s more of the initial power-up rather than a massive difference in power. Looking over the last few months of Garmin history for rides over 20 mins and 5 miles, this is my highest average wattage (214 vs 207) by 7 watts, but only my second highest max-average-watts (244 vs 258 highest 20-min average during the ride).

I also had actual breakfast – 2 mini sausage-biscuits (300kcal) and 3 six-inch pancakes (about the same). No syrup or butter. Powerade full-strength in one bottle, and half plus sugar-free green tea in the other… plus 20oz of gatorade mid-ride, plus a fried pie mid ride. It was 20 miles in before I opened the first bottle, but I’ve been pretty well hydrated lately. I definitely felt the slowdown before beginning the rehydration.

I was short on sleep, and had Advocare MNS Max E (though I didn’t have the CorePlex, the probiotic, nor the Omega. I added a single OptiMen multi tablet, and one TwinLab TriBoron Plus calcium). The MNS E is caffeine laiden, and I felt very alert. Perceived exertion seemed lower than expected, but it was still very obviously a hard push. The ingredients all look to be okay were I in a UCI race, but I can’t help but wonder about metabolites, etc. I couldn’t find anything on the USADA or WADA websites on labs for testing. They specifically don’t test supplements. More research is warranted.

Leaderless Ride

Sharon was ill, so a few of us rode from the duck pond.
Karl, Kathy, Jim, Becky, Darrell and I.
Was a pretty easy pace other than a couple hill sprints for fun.
We stopped at the Wal-Mart grocery-only at 2499 and 3040,
and stopped at the Farmer’s Market at I35 and Garden Ridge.
I’m missing a chunk from Wal-Mart until almost to LakeSide.
We were going to check out the Loozvil parade, but we were early.
Overcast for much of the ride was welcome.

MRI terms demystified

SAG – Saggital – From the side. Top of head is up, face/chest are left. backside is right.
AX – Axial – From the top. Face/chest are up. Backside is down. Patient right is right & patient left is left.
COR – Coronal – From the back. Top of head is up. Patient right is right. Patient left is left. First image is front of body.

T1 – Short timing – Pulses (TR or Time of Repetition) are less than 1 second apart. Return signal (Time of Echo) is less than 30ms after pulse. This is weighted for showing proton density (PD), which means fluid and complex molecules.

T2 – Long timing – TR over 2 seconds, and TE over 80ms. This picks up lower density structures better, but rapidly flowing fluid, especially arterial blood, will already be out of frame before the echo is returned. This picks up MS better, because of the high density signal from the plaques and lesions is strongly contrasted by the low signal from the CSF.

FLAIR – Fluid Attenuated Inversion Recovery – Often a T2 image is really a high dynamic range image created from both T1 and T2 echoes. This is used to suppress the CSF signal, while still picking up the details from T1.

Signal differences
Different types of anatomy and pathology return different levels of brightness or darkness. Comparing T1, T2 and FLAIR signal strengths can determine what type of mass exists at a specific voxel (volumetric pixel). This can be compared with reasonable physiology for the area to help provide diagnosis or indication for further assessment.

North DFW Group Saturday Rides

These are the summer times.
These usually move an hour later with the time change.
Join the clubs’ online forums (or facebooks where availble),
since sometimes ride leaders are ill, have other plans, etc.

Carrollton Cycling Club has two standing Saturday rides:

  • Al has a 7:00am, 45-60 mile ride, at a challenging pace, starting from Coppell’s Andrew Brown Park – East.
  • Valerie has an 8:00am, 38 mile ride at a moderate pace from the Carrollton Gazebo on Broadway, south of Belt Line, close to I-35E.
  • http://www.carrolltoncycling.com/ccc_rides.html
  • Sharon has a pseudo-official group ride at 8:30am from Cadence Cyclery at a C-group pace. If newbies show up, it’s a 10-mile loop. Otherwise, the regulars tend to ride 30-70 miles around 15mph average, with a food stop on the way back in.

Texas Flyers (Flower Mound) also has two Saturday rides:

  • TX Flyers has a 7:30am, intermediate ride at 16-18mph from from Downing Middle School on Waketon and Bridlewood.
  • TX Flyers has a 9:00am social ride at 15-17mph from Downing. Usually meets the first ride at Cachette.

Corinth Cycling has three Saturday rides:

Shawnee Trail Cycling Club (Frisco) has several rides:


IBC B-Group Norm

Steve was working, so A-Group was self-lead. Norm was a little under the weather, so he lead the B-Group, which I rode. We didn’t do duck-slime. Sharon was a little under the weather, so she lead the C-Group. I’m a little under the weather. I think maybe we caught something at HHH, or the sleep disturbances Friday night + the long ride Saturday + the dust from cleaning the cabin might have just hit all of us a bit.

Anyway, this was a good ride. Really happy. I’d have liked to not ride the brakes on the downhills, and maybe not sprint at 21mph on the uphills (eyes Abdul and Xavier suspiciously). Even so, the pacing was good overall, and most of us rotated through the front slot, with only a couple of the stronger riders (A-Groupers) pulling more than a few miles.

It was just a teensy bit overcast, and the sun is dropping lower on the horizon, so it didn’t FEEL super hot.

Norm is a good ride lead, setting an example pace, then stepping out of the way except when there’s something to address (too fast, mechanical, whatever). A++ would ride again, though I missed some of my regular ride partners who stayed loyal to Sharon and rode with C-Group.

Strava Connect?

I accidentally deleted my upload bookmarks, because in Chrome, “T” means new tab in one context, but delete in the bookmarks context. Really stupid. As in ridiculously stupid. As in, how does the product manager remember to breathe, or not to eat their own faeces, stupid.

Anyway, this precipitated me finding the Strava (strive!) upload link, which now recommends linking to Garmin Connect. Now, Garmin Express magically uploads to all of the places I care about.

On the flip side, it’ll sync before I put in any details about the ride… Meh. Whatever.

Looks like power, hrm, timing, and laps all made it over.


HH100 timing chip

At HH100, there were 15,000 registrants,
and 3198 completed the 100 mile course.
Here’s my timing chip results for bib 2942:

2014-08-25 IBC new route

recovery ride. left gps at home. Used phone. Garmin is imported from the Strava TCX export, missing laps and pauses.

Power data is broken, with more drops than connections.
Not sure why, if that’s a Stages BTLE issue, or if my phone couldn’t catch the data from my back pocket.

Also, no HRM data because I only had an ANT+ strap.

My right shoulder is in pain, and very sore from HH100. I had a massage today which helped my legs a bunch, but my shoulder is from a pinch/abrasion in my neck. Low back is sore too. Need more stretching. I haven’t taken NSAIDs yet, because that reduces rebuild based growth/improvements. Maybe tomorrow.

Not sure if I’ll ride Tuesday.

2014 HH100.org Hotter’n Hell Hundred

Had a great time over the weekend with Sharon’s group. My ride itself was from 07:05 through 13:40, with prep time up front, and stops on the end.

We had a bunch of people in the Coyote Den, and it worked out pretty well. We had too much food, but better than too little. Becky’s potato was eventually found. Sharon’s bike survived a side-swipe by an idiot. Kathy survived being bowled over by an idiot. We had a few people cramp up, but all but 2 of our group finished the 100 miles.

Overall, ride support was great. Lots of snacks, pickle juice, ice water, ice powerade, a few sno-cone stops, lots of medical, sag wagons, etc.

The last 20 miles are into the wind, up-hill, with the heat turning up. The Dean VFD had a couple of great stops for us in the worst parts of it, plus water bottle ride-bys that were great.

As an event, we made a pretty big mess, and I both apologize for that, and appreciate all of the clean-up that is probably still happening.

The last 5 miles were sneakily marked as 5 kilometers. Someone got confused. Where it said 5km / 5000m left, it was really 8000m left.

We’re thinking, next year, we should do the 100k vs the 100mi, because the 100k passes through the airbase.

Also, my SMS to facebook wasn’t working, and T-Mobile is garbage. All of the AT&T users were in great shape, posting photos to Facebook, and I had to turn off email checking just to keep my battery from chewing up. Lots of times I went from 4G down to LTE, to GPRS, to even NO SERVICE. *sigh*
