Turbo Sustain

Aim:
10 min of elevated pace on turbo
Session:
5 min easy warm up
10 min of steady intervals
10 min at race effort (or as near as I can manage on a turbo)
5 min cool down

Note:
I still can not get anything like the same effort or HR levels on the turbo as I can easily get on a "real" ride.

Go figure?
