10-20-30

From the University of Copenhagen (Gunnarsson & Bangsbo, 2012): each minute is 30 seconds jogging, 20 seconds moderate and 10 seconds close to flat out. Three five-minute blocks with two minutes rest. Runners got faster on half their usual training. Best outdoors or on a bike.

How to pace it

Each minute has three gears. Jog for 30 seconds, run 20 seconds at a pace you could hold for a while, then give the 10 seconds nearly everything. The sprint should feel fast but not reckless: it comes five times a block, fifteen times in all.

Who it’s for

Runners who want a short, hard session. In the study, moderately trained runners replaced part of their training with 10-20-30 for seven weeks, ran about half their usual volume, and improved their 1500 m and 5 km times.

Running it as a group

The gear changes come every 30, 20 and 10 seconds, too fast to shout. The voice calls each change with its effort, steady or all out, so the whole group shifts together.
