I decided to make my own plan this winter using the Joe Friel Cyclist’s bible. Base 1 went well, and now I’m in a recovery week. The plan calls for a T1 workout – an Aerobic Time Trial – on Saturday. It just says ride 5 miles @ 9-11 beats below LTHR. IMO there are so many variables this test is almost not worth doing.
Has anybody done one of these before?
I recently got a PM for my road bike, so might do a 20’ outdoor effort.
