i don't know if i've ever sweat as much as i did this morning. there were times when the wind was blowing drops off my helmet like i was riding in a rainstorm. it's a good thing i was riding early in the morning. if i tried the same work out at 95 degrees (predicted high) and 81% humidity instead of 73 degrees, i'd have died. as it is, i'm just tired. tired beats dead most days.
i rode intervals again. after a mile warm up, i rode three sets of five - half mile hard effort, half mile rest. the rest between the first and second sets was longer than the rest between the second and third. (19.31 miles @ 17.1mph)
