Try this one-hour ride from One-Hour Workouts!
This session steps up the leg speed every 5 minutes while holding a constant speed or effort level. Ideally this session should be done on an indoor trainer where you can accurately manage your cadence. Cadence builds develop great leg speed and endurance with 10-rpm jumps every 5 minutes.
You’ll find that although you hold a constant rpm and pace on the bike, your rpm and heart rate will typically go higher as the cadence increases.
As you become stronger, modify the up-down tempo set to ride at race pace and eliminate the recovery interval.
