Huntsville Omnium Day 2 – Wrapup

July 16, 2012 at 12:42 pm Leave a comment

Summary – 2nd in the masters 35+ criterium, 3rd in the pro/1/2/3/4 combined criterium, plus 5 points on a bonus points prime gave me just enough to tie Beth Hollingsworth (Velocity Pro Cycles) in the overall, combined omnium. With the tiebreaker being the time trial time, I ended up winning the tie breaker to take 2nd in the omnium behind Chris Brown (Litespeed – BMW).

Masters 35+ criterium – this race started out fast, so fast that the field split at least once before the first prime. The field was back together by the first prime, but I wasn’t in good position to go for it. A couple laps later, however, there was another prime that I thought was for a bouquet of roses. In a field full of masters, I thought that this would be hotly contested (to bring home to give to our wives) so I jumped really, really hard on the inside on the short flat stretch before the final turn. I was sheltered from the cross-wind by the pack when I attacked and then when I made the turn I had a strong tailwind. It turns out that I jumped hard enough that nobody else contested the prime, and I had opened nearly a 10 second gap by the time I won the prime — (unfortunately, after the race, I found out that it was a gift certificate to a restaurant named Rosie’s).

About halfway through the next lap, I looked back and saw Chris Brown closing in fast bridging the gap by himself. When he got close, I jumped back up to speed and together we worked to try to fend off a chase group of 5 riders that had split off of the blown apart field. We worked together well, but the gap stayed at just a few seconds for several laps. Then finally after several really hard laps, the gap started to increase by a second or two every lap so that it eventually got out to 20 seconds. But then it started coming down again — by 5 seconds in a single lap to take our gap back down to 15 seconds. Then, the next lap it was down to 13 seconds. Fortunately, by this point we only had five laps to go in the race. So we turned on the gas one last time and held it to the end where Chris took the sprint.

Monte Sano – climbing
The Rapha Rising climbing competition had also begun today so I headed out after the masters race to do some climbing. I ended up breaking a spoke at the bottom of Monte Sano, turning around and getting my spare wheel, before doing the climb again. It was a long, steady, gradual climb but my legs were tired and I needed to rest for my the pro/1/2/3/4 combined crit later in the day so I only did the climb once. I’m in a deep hole for the climbing competition right now, but I am hoping to make up ground by Wednesday.

Pro/1/2/3/4 combined criterium
One of the unique things about the Huntsville omnium is that it is combined over all the categories. And to finish the combined omnium off, there is a combined Pro/1/2/3/4 criterium for the last race of the day. By the start at 2:00 – it was very hot – well over 100 degF in the sun on the start line. Combine that with the humidity that somehow hadn’t burned off from the morning, yet, and it was going to be a sweltering race that I wasn’t sure I could finish.

On the start line, as the race official said “go”, they also rang the bell for the race’s points prime – 10 pts, 5 pts, and 5 pts for 1st, 2nd, and 3rd. I was on the front row so I thought about just taking off and going for it from the gun — especially since Chris had started farther back. But I also knew that it would be a long race and that if I won the prime, I stood a very good chance of not being able to finish the race at all. So I hung back in 2nd and 3rd position as a couple riders drove the pace pretty hard anyway. I started the sprint for the prime, but Chris was able to come around me just before the line. I figured that the race was over and that Christian Parrett (Global Bike) and maybe one or two riders would bridge up to us for the break. But instead, the field came back together.

Shortly after that, Christian began a series of attacks that eventually saw him get away solo. Chris’s teammate Anders got away in a chase group of 3. But one of the riders got shelled making it a chase group of two. Our average pace in the field slowed way down as there would be an attack and then when the attack was chased down the pace really dropped. After only 20 minutes into the race, Christian lapped the field which was down to less than 10 riders by this point – but the chase group of two still hadn’t caught us. So Christian went immediately to the front and began driving the pace. He very slowly started extending the gap on the chase group (we had been getting splits to the chase group behind us). At one point the gap from the chase group to the back of the field was only 20 seconds.

I had won a couple field primes during this time, but then while Christian was driving the front they announced a $230 giro helmet prime. I need a new helmet, so I went really hard for this one. Will Fyfe (Birmingham Bicycle Company), however, just got me at the line. Our effort for the prime, however, shelled some more riders from the group and later when Chris attacked I was able to go with him. He was in an awkward position because he couldn’t work too hard or we would catch his teammate. At the same time, though, it was safer to be off the front then contesting the field sprint. So we settled into a rhythm that looked like would keep us in front of the field but behind the chase group of two.

The chase group had been out front for a long time in the hot conditions so we ended up catching them with about 5 laps to go. This put four of us working together to stay in front of the field. In one of the corners, I felt my rear wheel slide a bit. It felt like I had a flat tire. But I bounced on it and it didn’t seem to be bulging out too much so I kept on going. By three laps to go, though, the tire was rolling on the faster corners. I went to the front to drive the pace so that hopefully I would have enough time to get a wheel from the pit and stay in front of the field since there was no more free laps. But in the end I decided to just risk it since it seemed to have enough air to not be rolling on every corner. Fortunately, the sprint at the finish didn’t start in earnest until after the last corner and I was able to give it max effort up the hill to finish just behind Chris for 3rd place. Here is a picture I got right after the race – I’m guessing that the slow leak had taken it down to maybe 40 psi by the end.

All the data
With five separate races this weekend, I have gobs and gobs of data. So I’ve highlighted what I consider the most interesting data and then put the rest into a gallery. First, I set three new power records this weekend … the first was during the masters road race over the range from 17″ (916 watts) to 20″ (878 watts). The second was during the time trial over the range from 1’07” (607 watts) to 1’30” (545 watts). And the final power record was during the P/1/2/3/4 combined crit (probably sprinting for either the points prime at the beginning of the race or the giro helmet prime) over the range from 2″ (1107 watts) to 16″ (930 watts).

The next two most interesting data items are the heartrate plot and summary for the Pro/1/2 road race Saturday morning. This was a particularly difficult race to start out the weekend with!

Pro/1/2 heartrate and power plot (power smoothed with 30second smoothing filter)

The time trial power plot is interesting … speed data is from GPS, but it looks like there is a second in the middle where my Garmin dropped the power reading right around the time that the GPS-based speed was getting goofy. I wonder if it was because the Garmin was devoting more processing power to trying to pin the GPS signal and dropped the power reading. I stayed big chainring the entire time trial and never stopped standing so my power should never have dropped to zero.

Finally, here is my lap data from the two criteriums on Sunday.

Long commute home Interesting time space thought - if you see this pic within a minute of me posting it, then I will be at the crest of the middle ridge. A little bit more challenging than normal getting this angle of my bike at the cliffs today.
