This set has been compiled to allow a good percentage of the session to be completed at the upper Z3 / lower Z4 'Sweetspot'. No big power outputs this week, but be prepared mentally to maintain a 'solid' effort for extended periods. Main set is 7 * 4:00 at Sweetspot with 2mins recovery - the slight twist is that each Sweetspot block is sandwiched by 15 seconds just above FTP at the start and finish, to simulate a strong start / finish which may happen (even if not planned!), in a race.
