I'd like to add another quality session into my week, but not sure where best to fit it in. Want to improve for the weekly evening TT
TSS usually 550-600 a week. CTL hovering around 85.
Week is generally :-
Mon - 40mins commuting
Tues - 40mins commuting. 10 mile TT (1h40mins total including ride to/from and warm up)
Wed -40mins commuting
Thur - 40mins commuting. 1h40mins training ride (v02max and threshold intervals)
Fri - 40mins commuting
Sat - Endurance road ride 3-4 hours.
Legs are generally dead on Wednesday and Friday after a hard session, and found I can't do anything hard on Sun/Mon or else I feel it in my legs come the Tuesday TT
