Notes
71F 91%H 68DP, at the Silver Comet, doing 6e+8MP+4cd, using 11:05 for easy, and 9:50 for MP, heat adjusted to 71F = 10 seconds for easy and 9 seconds for MP, so easy = 11:15 and MP = 9:59.
For the 8 at MP I averaged 9:58.9 (how is that for close), HR = 124.5, with average cadence of exactly 180 using metronome at 178. Successful day!
