Thanks for the follow up, I really appreciate it!!
20 min time trial test?
173
first 30 mins of a 50 miler race
170 (avg. of 170, 170, 169, 171, 171 … values from 50 milers to 100km races)
2 hour xc race?
never riden one, as an approximation may serve these values from the first 2hrs of 50-60miler races:
164, 163, 163, 164 –> avg. 163.5
50 miler race?
162, 162, 162 –> avg. 162
pretty scary how close all those values are considering how different all those courses werer …
