For a definition of these terms, look at my last entry on this blog. The first thing that stands out to me about these files is how low the power is. Every one of these riders is capable of producing more power than they did here but the technical sections make it difficult to use that power. A good technical rider will spend more of the time pedaling and less time coasting. Kyle is certainly the most technically proficient of these riders and he is able to come much closer to actually producing the power he is capable of producing. However, it is important to remember that most riders will fade in the later laps of the race so with only 35 minutes of data, Kyle's numbers are most likely a bit high.
The other thing that stands out about these files, at least compared to a road race or criterium is how low the cadence is. This is primarily because a lot of time is spent coasting, usually just before obstacles or technical sections. However, cadence will be lower even when pedaling during cyclocross because a bigger gear will generally make it less likely that the rider will lose traction.
More to come later on how we can use these files to better identify riders' strengths and weaknesses and design individualized workouts and training plans that can help maximize their potential.
Mike and I plan on being at a lot of cross races in the upcoming weeks, so if you are there feel free to stop by, warm up on the CycleOps trainer and demo one of the wheels. Here's the schedule:
November 10th: Beacon Cyclocross, Bridgton, NJ
November 11th: Highland Park Cyclocross, Highland Park, NJ
November 17th: Mercer Cup Cyclocross #1 (USGP #3), Trenton, NJ
November 18th: Mercer Cup Cyclocross #2 (USGP #4), Trenton, NJ
November 25th: MABRA Championships, Taneytown, MD (tentative)
December 1st: Carlisle Cross Classic (MAC #5), Carlisle, PA
December 2nd: Capitol Cross Classic (MAC #6), Reston, VA
See you there!
