I'm finding with my power meter, if i take more then 1 day off my power output goes down for several days. well at least i can't maintain it, L 4 or longer periods of L 3 as i do usually. last week i rode 5 days. went hard fri, Sat, Sun,. Sunday i did a break on a big group ride of about 70 riders. i was never able to stay away always got caught but this one stuck big time.. this was the first big group ride since i been training with power. any way since that ride was hard 239 watt avg NP265 (3 hours 10 min, my PB for that length of time) i decided to take 3 days off. Thursday i rode endurance for 1:30 min. wow slightly sore legs after that easy ride, more so then last Sunday. today Friday, i was gonna ride 1 hour L3 with some 450 watt sprints every 3 min for 10 sec, only could do 30 minutes. i have always been able to complete that work out. i blame it on to many days off. my data shows it every time. i really ride best if i ride easy rather then take a day off. just my experience with more then a day off.
