Day 1 – Crossroads Classic – Concord Criterium

Race Summary
This race was a new first for me … at just over 0.3 miles long, this is the shortest criterium course I have ever done. Despite the short distance, the course was safe with wide corners that you could carry your speed through. Turn 4 was the sharpest and most awkward corner that required the most acceleration coming out of, but even then you still could take the corner at well over 25mph. All the other corners, you could take at full speed (30+ mph on the faster laps). I ended up in two very nice looking breaks about halfway into the race and then later in the race. Both breaks were away for several laps, but both came back to the field. Ben Zawacki (Mountain Khakis) counter-attacked the second of these breaks and got away solo, eventually settling into a rhythm just behind the field less than 10 laps later to take the win solo. A couple other riders slipped off the front chasing and stayed away. The rest of us left in the field (maybe 30 or so riders out of 80 starters) were sprinting for 4th place. I ended up 18th wishing I had been more aggressive with 5 laps to go to be farther to the front when the pace ratcheted up for the final laps.

The details
Jockeying for a good position started before the race. I missed out on that battle, though, thinking that we had plenty of time to get a few practice laps of the course between the end of the 3s race right before ours. So I was on the backside of the course and joined in with the 3s on their cooldown lap only to find that the start/finish line was already packed with Pro/1/2 riders 4 or 5 rows deep. I slid in on the left and ended up starting 4th row. I had a good start, though, because the guy in front of me clipped in great but just about everyone else around him struggled to clip in. I was probably only 20 riders from the front by the 1st turn.

Keep in mind that with the scrum for the start line, we didn’t do any practice laps. So the first time I saw the corners was during the opening laps, which were pretty crazy. I hadn’t worked up the craziness courage yet to really rail the corners so I slid from about the top 20 to maybe somewhere in the middle of the group. It was hard to tell, though, because with the fast speed and constant turning you weren’t able to look much past the rider in front of you to figure out what was going on. And it was impossible to look behind you. I never once looked behind to see where anybody was – even when I was later in a couple breaks! I tried to gauge the race from Chad Andrews as he was announcing, and it sounded like Team Mountain Khakis and the Colombian National team were trying to get a break established very early.

I started to move up after maybe 15 laps or so when riders coming off the front were getting tired and looking for recovery. Also, even though the lap speeds stayed relatively constant, the group started to bunch up in two spots on the course. I took advantage of those two spots to pass five or six riders at a time. Sometimes, it didn’t work too well and I would get cut off in one of the corners or pushed to the outside if I was on the outside and end up losing all those positions back. I saw an opportunity about midrace to pass everyone and go straight into an attack. From the segment data (heartrate and power), it looks like it was maybe around Lap 34, 35, or 36. Chris Harkey (Hincapie Green) drove the break for the first two laps by himself. Then we started rotating pretty well and extended our lead to maybe 10 seconds? I was really hoping that we would see the back of the field soon and motivate us to lap the field. Unfortunately, the field was chasing hard and brought us back. A few laps later I found myself in another break. This one didn’t last as long, but it took us into the portion of the race where it started to rain. We were caught right as it started to rain. This is when Ben Zawacki put in a solo counter attack. I was thankful to be at the front for the light rain because it was just enough to make the course slick. I heard a crash in Turn 1 shortly after my own wheels started to slip in the corners. Then it stopped raining, and the course was completely dry by the time we hit five laps to go.

With Ben just off the back of the field deciding it was safer not to lap, Mountain Khakis was free to setup a leadout train and kept the pace really high for the last five laps. There wasn’t much change of position at all. I ended up 18th in the race which must have been about 14th in the field sprint with a couple riders slipping off in pursuit of Ben and staying away until the end.

Overall, I was happy with the race, but frustrated by the finish. My mistake was in not being aggressive enough with about 5 laps to go. If I had expended the extra energy at that point to move up, then the group’s momentum would have kept me closer to the front instead of sprinting somewhere mid pack to finish 18th, three spots out of the money. Oh well! Looking forward to tonight’s race which is a figure 8 (barbell) course. Should be fun!

Grafton Criterium – Tour of America’s Dairyland – Day 3

Dropped a LOT of money at the bike shop today to buy replacement pedals.

Today started out with a trip to Wheel and Sprocket – very nice bike shop based out of southeastern Wisconsin. I picked up the Speedplay pedals shown above for $352. With that fresh on my mind, I was really hoping to win some money in the race tonight at Grafton. I finished 14th last year, but this year I rode a really good race until 2 laps to go and finished out of the points and out of the money. The highlight of the race turned out to be taking 4th in the mid-race USA crits points prime. I missed the counter-move that ended up sticking even though I was right there when the move went. I was still recovering from trying to go for the prime and then being in a five-man break for a lap. I fought hard to stay towards the front, and with two laps to go I was sitting third wheel. Unfortunately I got bumped kinda hard going into Turn 5 and started losing position from there all the way to the end of the race and finished maybe in the top 40 or maybe not. Update – just saw the results – 51st. Wow, there were a lot of people in front of me.

Here is all of my power and heartrate data…
Strava map highlighting one lap of the course. Here is the link to the interactive Strava data – http://app.strava.com/rides/763664

One interesting note about the power graph below is how visible the mid-race prime and break are — particularly in terms of cadence and heartrate — much, much smoother in a break than accelerating, braking, etc… constantly in the field.

Finish of the women’s race

This looks dangerous – bike swallowing railroad tracks encountered during warm-up ride (not in the race)!

Sandy Springs crash, videos, and race report

Summary – racing well, but missed break which lapped the field. I was working hard to stay at the front with 2 laps to go when my front wheel started to slide out on the fast downhill turn #3. I straightened up to stop the slideout, but that meant that I wasn’t going to be able to finish making the turn at 32+ mph. I ended up slamming into the barriers shoulder first at 32.3 mph according to my iBike. Here’s the same explanation in video form at the hospital:

I am incredibly sore on both sides and the back of my neck. Here is a picture showing the bruising and swelling around my neck and where the helmet straps cut into the skin. Same thing on the other side of my neck. Ouch.

Dilworth USA Crits power/heartrate data and quick report

Tough race today. Still not feeling 100% but happy to survive with no cramps and wrist not as sore as the night before. I started midpack and then stayed there for most of the race, drifting towards the back all too often and then fighting my way back towards the front. The key feature of the course was a tight greater than 90 degree turn at the bottom of the hill to take you back up to the start/finish line near the top of the hill. This is the source of all the power spikes in the data — accelerating out of the corner and up the hill. Kristine got some great video, and I will have those uploaded by the morning. Here’s a video of the finishing sprint:

Spartanburg power/heartrate data and quick race report

Fun, fast course last night in downtown Spartanburg, SC. This was the fifth of seven races of the USA Crits Speedweek. Very smooth race on a short four corner course. The start/finish stretch had a short section of brick cobblestones and a few manhole covers. This was the only part of the course that was rough. Everything else was super smooth, and we flew through 70 laps in 1 hour 15 minutes for an average lap time of just over 1 minute.

I started mid-pack and worked my way towards the front, but got swarmed in turn 3 a couple times and found myself back in mid-pack. Then with about 15 laps to go, UHC and Kenda started to set up the lead-out trains for their sprinters. I was still able to move up and passed people as they came off the front or sat up. By the end, I was able to finish 44th. I was happy to finish because I wasn’t sure if my sore leg was going to cramp up and how my wrist would hold up. Both were fine, and I was happy to get some finishing points for the series.

With no crashes, flat tires, or broken spokes, I was able to record power data on my iBike for the entire race.
