I have been following a training program for the last couple of years that involves 3 hard weeks, followed by a recovery week.

I am considering trying a program that would involve 10 consecutive days of hard training, followed by 4 recovery days (with maybe a few, short, easy workouts during the 4 recovery days).

The overall volume and intensity should remain the same.

I appreciate-
Opinions?
Experiences?

Current (3 week hard/1 week recovery)- The hard weeks involve 18 hrs/wk with one day off, the recovery week involves 8 hrs/wk with 2 days off.
Proposed (10 days hard/4 recovery)- 31 hrs in 10 days hard, 1 day off, 1 day with 20 minute each SBR, another 2 days off)
