I'm following the daily recommendations for a marathon on December 3rd, and this week I've done: Monday: Rest Tuesday: 45' Sprint 7x10" Wednesday: 40' Thursday: 75' Friday: 30', it was time to rest Saturday: 34' Sunday: 43' Vo²max. It seems to me little training... when I am at an optimal load level, good sleep score(82), low stress... as you see?
