iBike graph for my entire ride – annotated from within iBike (click to enlarge)

Happy days are here again as I have remounted my iBike Dash with Power. Props to the good folks at iBike who repaired a broken enclosure bracket on my iBike Dash device and a broken LCD screen on my iBike Gen III device – for free, even though my Gen III was out of warranty. Those of you who know me well (or even partially well), know that I’m pretty much obsessed with topographical maps, bike riding, and analyzing bike ride data — especially climbing related data. The screenshot above is from my commute home from work.

The iBike Dash clearly has the best in-ride graphical user interface of all bike computers/GPS devices — making full use of the color iPhone touch screen (see this post for screenshots – http://toonecycling.wordpress.com/2011/04/21/equipment-update-ibike-dash-power-meter-wheels-and-tires-galore/). But the best two features of the iBike for me are the internal gyrometer for measuring slope and the iBike ride analysis software, which in my opinion, is the best graphing software for displaying power, cadence, elevation, heartrate, and slope all on one screen. The slope is obtained using an internal gyrometer, which is much more accurate than a barometric obtained gradient as the barometer can never catch up with the slope changes in a severely rolling area (such as where I live).

On my way into work today, I figured out a topic for my next journal article — developing an algorithm for analyzing ride data from any device, combined with data reported from other devices for the same segments, combined with survey-based and/or radar acquired elevation data to come up with a “best fit” elevation profile. On my way home from work, I was inspired to do a climbing route with some of the steeper climbs on Shades Mountain and Little Valley Mountain including a nearly 30% driveway off of Altaloma. Here is the topocreator map:

About the journal article I am going to write, look at the complete iBike stats below, particularly note the “Climbing” amount. The iBike only registers 4000′ of climbing, whereas the Garmin registered nearly 5700′. The zoomed in iBike graph below the stats shows why. Even with a 29% gradient climbing at least 30 feet, the barometric sensor only registered a 2 foot climb for the entire driveway since I turned around and immediately skidded my way back down the driveway across the road and into the grass on the other side (I can’t imagine the wear and tear on the brakes of whoever lives in that house). Even the iBike gyrometer couldn’t turn around fast enough from the extreme climb to the extreme descent with it only registering a 2 or 3% descent even though it should have been -29%. Interestingly, the Garmin registered 30 feet of climbing for the driveway and 25 feet of descending even though I noticed that the % gradient was pegged at +17% the whole way down the driveway. I guess the % display only updates itself at a slower rate than the internal elevation recording.

Schlitz Park Criterium – Tour of America’s Dairyland – Day 6

Strava map highlighting one lap of the race.

This has to be one of my all-time favorite criterium courses, although I would not want to race it in the rain. Fortunately for us in the pro men’s field, we dodged the thunderstorms and raced on a completely dry course. This was not the case for races earlier in the day, including the pro women’s field (see pics in the gallery below). The race starts on Pleasant St at river level (Milwaukee River). The first turn takes you onto Brewer Hill where you climb all 68 ft that course gains in one shot. Then after a flat section across the top, you dive down through a series of twists and turns to make it back down to Pleasant St for the finishing sprint. In the middle of the race, I was thinking how beautiful it was to be following a single file line of riders through so many turns at speeds approaching 35mph on the downhill series of turns lap after lap. This was the most technical course of the entire series, and there were no wrecks!

Here is how the race played out – a small break established itself within the first few laps of the race. They stayed away for the entire race, but never lapped the field. Towards the middle of the race, I tried to get into a chase group. This lasted for a lap. Then with 5 laps to go, another move went off the front of the field. I saw it but hesitated. Then I decided to jump anyway and rode the rest of that lap and part of the next one solo trying to chase back onto the chase group. It was all for naught though, because the field caught me and eventually reeled back in the chase group with 3 laps to go. I had burned a lot of matches with that move, but I still really wanted a top 20 result so I fought hard to move up on the last two laps and ended up 19th.

iBike stats – a couple interesting things highlighted in red. The interesting thing about the braking is how little there was of it. You really didn’t have to brake that much anywhere on the course because everybody was so smooth!

Greenbush Road Race – Tour of America’s Dairyland – Day 5

Notice anything missing in this picture??? Answer – my iBike came loose on one section of bumpy road. There was no way to tighten it back up while riding so I had to wait for one of the screws to come completely off. Then I could spin the iBike around to unscrew the other screw. Finished the race with the iBike and my iPhone in my pocket.

This was a fun race course through the Kettle Moraine State Forest area near Greenbush and Elkhart Lake. The course was rolling with several steep rollers having gradients well over 10%. I got into an early move that lasted 3/4 of a lap. The field brought us back, and I drifted too far back in the pack so I missed the counter attack and a subsequent chase group that hung in front of us for a while. Then as people in our group started to pull out of the race, the chase group left the field for good which meant that the rest of us were racing for something like 12th or 13th. Still, I wanted to make a race of it so I tried to get in a few moves, and I tried to keep the pace in the field rolling.

On the last lap, Steve Tilford attacked after exiting the forest. A couple guys bridged up to him, and I was sorta in disbelief that I had just missed another move. An ISCorp rider attacked into the headwind a little while later. I was at the front and determined not to just wait for a field sprint. So I attacked to bridge up to the ISCorp rider. I attacked hard and was able to get away cleanly. I looked behind and saw that the field hadn’t responded so I poured everything into it not saving anything for the sprint. I made it to the ISCorp rider right as we were making the lefthand turn to take us through a long section of crosswinds. We worked hard together and could see the field strung out behind, but they had waited too long to start chasing. Up ahead we were closing on the break of three who appeared to have merged with the remnants of the chase group that had been gone since the second lap. I need to see the results to see my exact placing to determine if that is what happened. In any case, we couldn’t quite close the gap to that group, but we stayed ahead of the field. I couldn’t compete with the ISCorp rider in the sprint after doing a lot of work so I sat up and eased in just ahead of the field.

Waukesha Criterium – Tour of America’s Dairyland – Day 4

Finally, I made it into the top 20 to score a point towards the overall omnium. I am excited about the road race tomorrow with its double points and long distance (about 80 miles). I had a great warm-up ride with lots of climbing up some very steep hills in Waukesha. None of them gained more than 150′, but several of them were in the 10-15% gradient range.

I had a not so good start somewhere in the middle of the pack. I decided to try the outside line, and it seemed to work on the six-corner course. I gradually moved towards the front, but then when the pace slowed down on one of the laps, I was able to attack from about 50 riders back from the front and move all the way off the front into a chase group chasing a break. The field was pretty much right on us, but from this point on in the race I was able to stay at the front of the field. I went with several moves and was hoping to be in position to go for a prime. The finish was great except I lost a few positions when I became convinced that the rider next to me was about to plow into some slower moving riders at the finish line. I eased up to consider my escape options for the pileup that was for sure going to happen, but at the last second he slammed on his brakes to avoid hitting them. Still, he was able to pass me in the process and a couple riders to his right also passed me literally on the line. Frustrating.

Here is all my iBike power data and lap splits from Strava.

Thiensville Criterium – Tour of America’s Dairyland – Day 2

My day started out with a wonderful breakfast at the original pancake house – pecan pancakes, great coffee, and fiesta omelette

And my day ended with this – a broken speedplay pedal!

Actually, the broken pedal happened about a quarter of the way through the race, and the awesome SRAM mechanics had me up and running with replacement pedals to hop back into the race on the next lap. I was placed at the back of the pack but was able to move all the way to the front by the end of the race. There was one big wreck on the backside of the course with 3 laps to go. The course went through a couple blocks of houses with nice grassy yards which turned out to be escape routes for riders in that wreck and also when getting pushed out going into Turn #5. That is one of the visual images from the race that will stick with me — a rider going off the course and riding down a small embankment into somebody’s yard and then out the other side to hop back on the course!

A break of three escaped with about 10 laps to go in the race? I ended up 33rd which meant I was 30th in the field sprint. I fought hard for position, but cramped coming out of the last turn. I had a good wheel to draft though and was able to coast with only a few pedal strokes behind a large, fast rider to the finish. Only 9 more days of racing left!

Shorewood Criterium – Tour of America’s Dairyland – Day 1

Today was the first day of the Tour of America’s Dairyland, 11 consecutive days of racing all over southeastern Wisconsin. First, the thing that probably amazed me most about today … I had to wear arm warmers and the temperature dropped into the 50s by the end of the race. Keep in mind that summer is supposed to start in a few days! Here is a picture of the temperature after the race:

59 degrees by the end of the race … at the beginning of summer???

And now for the race report, the course was a classic four-corner rectangular course with a chicane shortly after Turn #3. The road between Turns #1 and #2 was really rough. There were cracks, bumps, manhole covers, and more along the entire road. There was one bump high enough to launch you (and your bike) a few inches off the ground. I went over it a lot because it was one of the places to pass people. The rest of the course was pretty good pavement except for dips and bumps around manhole covers.

I started towards the front of the group and fought hard to stay there. I was a little tentative since this was my first criterium after my bad wreck at Sandy Springs. I decided to stay on the inside of all corners to maximize safety even if it meant having to accelerate hard out of corners. Still, there were a few close calls including one near-miss where the rider in front of me slammed on his brakes hard enough to lift the rear of his bike a couple feet off the ground essentially doing a reverse wheelie on his front wheel. I thought for sure he was going down and taking me with him, but he kept it upright.

Towards the end of the race, I was able to move all the way up to the very front. I think people were getting tired. With 3 laps to go, I got a bit swarmed though and never could move back up to the front. I fought to maintain my position and then passed a bunch of people at the end who had sat up. I’m hoping I squeezed into the top 30, although points were only awarded 20 deep. There is always tomorrow!

Here is my iBike power data:

This race was in Shorewood, Wisconsin – a northern suburb of Milwaukee. Beautiful town right along Lake Michigan. Check out the pics below:

New (not really) monster

Recall the Birmingham Monsters post that I created a few months back. Well, there is a new monster in town! Not really, as I have done the climb several times, but today I grabbed the stats on it so that I could include it with all the other monsters. My rough definition of a monster is any climb which exceeds 20% for some portion of the climb. Also, a related statistic is the Scanuppia Distance (which is the cumulative distance traveled on the climb where the gradient is greater than or equal to 17%, which is the average gradient for what is arguably the world’s toughest climb – the Scanuppia).

And here is the topocreator map of the ride I did today with the elevation profile. Note that I did three variations of the Oakdale climb with the Stoneleigh version being the first one. Also, I really enjoyed the Shook Hill climb again today from Rocky Ridge and then climbed it towards the end of the ride for the first time from the Cahaba River in what I called on Strava a “mega stair-stepper” climb.

Short very hot ride. Cahaba river at the lowest I've ever seen it - at Hoover east ballfields shortly before running over fresh gum and cutting the ride short to clean it off my tire. Today's rollercoaster experiment - 20 repeats with Garmin 1000 forwards and backwards. Movie theater roller coaster (top) and Green valley rollercoaster (bottom).
