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 1x9 unless I'm on hills. No

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 ...

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.

Lunch at Modmarket, a new restaurant. Apple maps had a massively wrong location for 3651 Justin Road. Also, notice the teleport from Wal-Mart to Silverthorn. I forgot to turn on my GPS.

Men's Ride

Sep. 1st, 2014 03:28 pm

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.

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.

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.

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.

SUMMARY: Becky borrowed Theresa's spare helmet due to forgetting hers. Three of us were late. Karl met everyone on Ripy. Ben and I missed both the start and the late-roll times. Ben dropped after 18 miles of catch-up speed. The group lagged where possible, and despite me missing a turn, I joined the group at the Airfield DR bus-stop.

Ref: https://www.facebook.com/photo.php?fbid=10203467275935868


Steve helped with routing/navigating because I had no real clue. We dropped Becky off at Corporate and FM2499. We met Mark's group at the end if Enzo's, and refilled fluids/foods.

Ref: https://www.facebook.com/photo.php?fbid=10154430050355627

At Briarhill and FM407, I got a flat. Rather than hold everyone up EVEN MORE, I suggested they roll on. I was only a mile from home anyway. As they rolled, I found out they were going to TCBY, but I still headed home anyway. I was totally beat.

My split averages don't seem that fast, but I had a lot of high speed during the chase. Also, the heat was really kicking my butt. Hard to keep enough salt. I was dizzy at the bus stop, and even after a pause, I never really caught a second wind.

I learned that if I offer a suggested route, that makes me the de-facto route master. I'm *not* a good navigator, mostly because I just don't have the miles to have all of these places memorized.

Bike Stuff

Aug. 8th, 2014 07:39 am
xaminmo: Josh 2016 (Default)
Lots of bike stuff done today.

The R600 from Mark is in good shape. Bearings "looked" good, but the old grease had shiny flakes. Replaced the bearings and grease. Cones and races looked fine. Braking surface is at probably 40%, so I scuffed it a little with a diamond file, and deburred it all around.

Replaced the missing spoke from the donor R550 and got lateral true in good shape. I'm not sure about dish, but it's within 4mm. There's 2mm hop (dip really), but I got tired of messing with it. The spoke nipples are at the hub, and I kept turning them the wrong direction. I think one of the spoke heads is going to pull through. It seemed a little deeper in it's seat washer than the others.

I have to say this is just about the tightest rim I have ever mounted a tire on. First bead of a gator was painfully snug, and I couldn't reposition the tire without popping it back over the rim. The second bead absolutely required a steel lever. On the flip side, it was really happy to take 120psi.

###
The R550 wheel is now missing 2 spokes, and the cone is damaged from the previous owner riding with the cones over-tightened. Also, one race had faint rust from having been wet, but it wiped out. I cleaned, repacked, and reset cone spacing. It's as good as it can get without putting money into it. Basically, it's a spare parts. It's almost exactly the same as the R600 wheel, though the R600 axle, cones,and hub seem a tiny bit lighter, and the dustcap is black plastic vs chromed plastic. The 550 finish is bead blasted, vs the 600 which is mirror finish.

###
Helped mark install some new Ksyrium Elite wheels. Adjusted lateral true, and sent him for a 1.85mm spacer (11-speed hub, 10-speed cassette). Adjusted brake tension and rewrapped the bar tape from the hoods up. Test ride was good, and his speed sensor is working properly.

###
New black bike is coming together. Installed the replacement chainrings on my DurAce 180mm Square Taper (1990s?). XT pedals installed. Rival brakes are installed and adjusted. Wrong color of cables came, but Ice Grey is good with Ben. I wanted black-carbon but I'm settling for plain black. I need to install the speed/cadence sensor and the saddle bag from the old black bike.

The only parts I need are cables and rear wheel. The black cables show up tomorrow. I may be able to pick up an R10S rear from Ben on the promise of helping him build up his project bike when all the parts come in. We'll see what a 20-spoke rear wheel is like with me on it, but ideally, it'd be temporary until my other wheels come back from Easton.

Then, all that's left will be fit/comfort adjustments, and maybe throwing the wheels onto a truing stand.

###
Picked up a 17mm cone wrench, and have blue and mavic spoke wrenches on order. Also, ordered some cassette spacers for 10-on-11, 10-on-8/9/10, and another gigpack of shop towels.

Was running late, but all of the groups rolled a little late.
A rolled as I drove in, and C rolled as I was putting my helmet on.
There was no B. I didn't have enough food, so C was okay, but the first half seemed slow.

I'm sleepy, and posting late, so I have nothing more to say.

Today's ride was planned to be 70 miles.  Riders included Mike, Steve & Theresa, Jim and Kathy, Becky, Karl, Glenn, Amanda and me.  From Highland Village, we took Old Justin instead of Crawford Ranch, and ended up 15 mins and 5 miles behind schedule.  From Robson Ranch, we shimmied over to FM165 and took it down behind Alliance Airport, across to old-town Roanoke, with Lunch at Twisted Root.

Group Picture:


Bikes Leaning on Bikes:


Glenn was cramping up, so he sagged back with 50 miles logged.  The rest of us For the ride back, we took 377 instead of Dove/Grapevine for a faster return. Maladies for riders included a couple dropped chains, 1 slow tire leak, some leg cramps, and two people with lower GI issues.  BUT, no one needed new shorts, and everyone survived.

ps, The weather was very nice. It did warm up, but we had lots of cool breeze throughout the morning.

It was a pretty good ride, even if Sharon wasn't with us. (See photoshopped evidence below!)

Strava is broken as of sometime after lunchtime, so only uploading from Garmin. Our route map looks kind of like a slug, with eyestalks. Went to see the Kildares, but Lewisville moved it inside.  There was not enough seating, so after snacks, we went to DQ, then ended the ride.  Temps were cool, and partly cloudy.

A great ride with Sharon's group. Sharon is the navigator and planner. Charles is the Gofer/Dufer/Pilot/Moral Support and most of all, the Grasshopper Remover! :) Also along were Becky, Karl, Steve, Theresa and me.

I started off finding my own cadence which was quite a bit faster than the group; however, around mile 18 they all caught me. Around mile 27, I dropped my chain and wrapped it in the rear derailleur. Took me till the rest stop by the Waurika Dam Bridge Road to catch up. I was pooped.

It was hard to keep salt and calorie levels up. I like going faster downhill, and maybe a little slower uphill. Most of the others were the other way around. We'd usually have a gap of about 100 feet as a buffer, but sometimes I had to use brakes.

We stopped at 30, 50, and 60 mile rest-stops. 60 had flavored ice, and it was good. That helped a lot. I got my second wind and pulled ahead. Karl zoomed, and pulled for a while. I fell off the back, and was passed by Sharon. Karl gave her a run for her money. The rest of the group wasn't far behind, relatively speaking. I think Sharon & Karl beat me by 3-4 mins, and the same for the rest of the group.

Becky's been very tired, and wasn't in the front for the last 15 miles. The tired PLUS the heat were too much. Around 15 miles, I opened a water bottle that was just ice, and dumped it into my shirt. That helped, but not as much as the snow-cone.

Steve and Theresa were a pretty steady, consistent pace. Steve pulled for quite a while too. Throughout the ride, we had several masses of riders join the double-paceline of the CCC group. Sometimes we were the minority of the group, but generally Karl and I... hrm... swept, and the others pulled. They got lots of thanks after the ride.

Overall, the ride had 624 bikers. If the Goatneck wasn't the same day, it probably would have been bigger. Support was great. Lots of volunteers, perfect snacks, facilities, etc. The best part was use of showers, hot tub, and pool at the Duncan Rec center after! Also, the Chicken Spaghetti was good stuff. Everyone was nice and helpful too.

A++, would ride again.

For HH100, I need to get a long-sleeved sun shirt, stay on top of ride-week stretching, pre-load salt, and get better with rolling snacks. But really, the key is staying cool. At 11am, it was just getting bad, and eating shaved ice, or dousing with cold water was the only way to stay alive.

http://omnitech.net/xaminmo/2014/07/26/2014-duncan-dehydrator/

Not sure what I think about the elevation. It's about 1000ft higher than Karl's. I used Baro, and he used iPhone 4S GPS. Both have issues. My + and - match, but who knows. We'll see if other people post stats for comparison. 24 seconds ago

Also, if I'd thought more, I would have added a couple of miles on the end so I could get another Grand Fondo ride for the year. *sigh*

Ride with several friends, and an unrelated but same surname friend-of-a-friend.
Music was country, but it was good anyway.
Karl and Sharon got photos by some squad cars lit up while the officers were roaming around the bank, looking for someone.

Today was a generally stressful day, so the bike ride was good.
I had a quart of fluid before I rolled, so I didn't need much in the first half of the ride.

The B group hung off the back of the A group for a while. We were less than 1 mile back until MacArthur, and then we stayed on their wheels until 161. At that point, the group split spread out, and ultimately into 3 chunks.

Meet-up at Cadence for the weekly long ride. Attendees included:
Theresa (invisible), Steve, Kathy, Amanda, Sharon, Becky, Karl, Jim, Josh (Me), Mike.


We rode down across the Grapevine Dam, through the airport, looped around the Grand Prairie race track, then up through Irving (including Las Colinas and Valley Ranch), and stopped for lunch at Hard 8 in Coppell.

On the way through Valley Ranch, Mike bonked pretty hard, and we were worried he wouldn't make it to lunch. He'd been off the bike for a few weeks, a little short on sleep, etc. However, after a Cliff Bar, he magically came back to life. Tired, but powered through just fine.

Amanda had an indexing issue on the rear derailleur. At first we thought maybe a bent hanger, or bent RD, but on closer inspection it looked okay, and the chain seemed straight. 2 twists of the inline barrel mostly fixed it. It probably needs a little more, or maybe just zero out the cable and re-clamp it. She was tuckered out and sagged back to a bike shop for adjustments.

Karl dropped the chain off the inside of the cassette. No spoke damage, and easy fix. He stopped pedaling really quickly, so it didn't wedge in behind the cassette. KARL! REMEMBER TO ADJUST YOUR LOW LIMIT STOP SCREW!

At a couple of pauses, I had to check email for work, but things went pretty well. My shoulders are sore. My hands are sore. Need new gloves, because I buy cheap, and my right hand is getting a blister. I remembered to go fairly salty on my beverages and food. Need to remember more tonight, so I don't cramp up on the airplane ride tomorrow night.

After lunch, we took Freeport/Lakeside/Garden Ridge, and then the Flower Mound trails up, came down Briarhill, and back through to Cadence. From my house to the second Cadence stop was exactly 73 miles, so the actual loop was 70.85 miles. Wheel calibration should be within 1%. Some of the others rode from further, so they had as much as +9.

Lots of good conversation, rambles, and not enough sprinkles. The humidity, and the wind from the south was pretty brutal, but we survived. Overall, it was a great ride.

Watts are complete guesses. If Calories are correct (FirstBeat/Garmin), then I averaged 195W. If Strava is correct, then 145W. If my calculator is correct, then 551. Nothing really factored in wind. So ready to have a wattmeter.

I checked on my Easton wheels, and they do have a squeak/problem. It's been 3 weeks, so I'm a little antsy. The plan is to ship them off late next week, and will probably get a factory replacement. I said I'd follow up in a couple of weeks. Wattmeter ordered 2014-06-09, so that would be the same time I would check to see if it's in (3-6 weeks).

Bicycling average speed is an important thing to know when joining groups. If you can't keep up with a group speed, then you may feel embarrassed, the group may feel resentful, and you might get dropped in the middle of nowhere.

Rough estimates are:
* Average speed is about 80% of your flat&level speed.
* Add 15% for group speed vs solo speed.
* Subtract 10% for each consecutive hour of riding.
* Subtract 50% or more for uphill speed.
* Add 100% or more for downhill speed.

The easiest way to figure all of this out is to use a GPS device, a calibrated speed computer, or a smartphone app to figure your average speed for a route.
