I rode a rather mundane TT at the Blue Streak on Tuesday, 22:27, 300w. Did 5 intervals of roughly 3-4:00today at 300-330 and then 30 sec on off at 400-420. That chart has a nice progressive downward slope to it, unlike my TT effort that had. strong start and very average middle to end. Need to work on the 20-30 minute power for 10 mile TT’s over the winter and will continue to hone the 6-15 minute power needed for the 5k-10k.
