Workout description

This session will help improve your pedalling efficiency and increase your cardiovascular capacity.

Most of the workout should be carried out at Zone 2 - roughly the power you would maintain on a steady road ride.

Not too hard, not too easy.

Carry out 3 x 8-minute blocks with 3 mins recovery.

Each 8-minute block should follow 1 minute at 90 rpm, followed by 1 minute at 120 rpm, repeated for the duration of the interval.
