My training stress ramp rate was about 4 points per week and judging by the way I felt this week that is about as much as I can safely handle at this point. It was 88.8 and ended at 113.5. I steadily built the long ride up to 7 hours and will continue on up to ten, but only adding on every other week. On the off weeks I'll do the five hour lake loop at my ultra-enduro race pace. Time for more on the bike strength work, speed skills, and sub-threshold intervals.
That pick of my dad and me is from 1968. Yeah, I've been riding bikes almost continuosly, in one form or another, for 40 years!
