The longer, harder route. Push a little, but not too much. Monday off. My tradition is to do the final taper on my rollers: Tuesday, 1 hr. zone 2 with 3 X 1 X 2 power intervals. Wednesday, 1 hr. zone 1 with 2 X 1 X 2 power intervals. Thursday, 45 minutes zone 1 with one 1' power interval. Friday rest for a Saturday century. Go to bed early on Thursday.
