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.
