Author: Hywel Davies

A tough interval session of 18 x 2 min efforts.

It's not too hard at first but the rest time drops by 5 seconds each rep. 10 intervals in the first set, 8 in the second with a chance to recover in the middle

It's often easier to push harder towards the end of an interval. This session encourages just that. Enjoy!
