Clip:

Some highlights in terms of "race events":
- I launch my teammate so he can try to bridge a gap.
- I sprint
That's it

First the overall race graph on Strava (the race is here in Strava). Nothing spectacular, speed in the mid-20s (blue line):


My fast lap is when I launch my teammate. It's fast enough that it's the fastest lap I've ever done there on Strava. I do about 34 mph in the effort then go really slow until I get caught. I still average 28 mph for the lap (and the effort and the slow bit are in the clip):


His lap when I launch him is impressive - he ends up 3rd overall on Strava, averaging 30 mph for 1:45 (1:45 lap). It's not in the clip since I wasn't with him:


My finish, which if you watch the video is in a slight tailwind sprint but with no draft. I jump early, I stay left of everyone, and I basically do my own sprint. Because I jumped early I didn't go a thousand percent. However it's fast enough to get into the Strava stuff; in real life the sprint is worthless. For the numbers people I did 1140w peak and sustained about 750-800w for 20 seconds; a typical all out sprint in a race is 1200-1300w and sustained 1000w for 20s, and an all out sprint in training is 1300-1500+, don't recall what I do for 20s in my peak efforts:


My average wattage is 175w for that race. 88rpm avg. I weighed in the 175 lbs range (5'7").

My bike was like this at the time (from a different race a month prior but same significant bits - wheels, tires, pedals, etc). I have aero wheels and I think they make a difference. The rest of it isn't very significant, i.e. if it works then it's fine. SRM to measure power. In other words nothing weird:


The race went 23.8 mph but the fast laps were in the 28-30 mph range.
Love the video. Number 701, 720 and I think 708 look like they might be from the Peerless group in Keene NH. (110 miles north) AKA as Heart of New England club. At least that was the club name when I rode with them in the 1990's. I still have my jersey from 1995 and it looks almost identical to what they are wearing.
