PacePack

Minute on/off

Ten one-minute efforts with one minute easy. Close to the 10 × 1 minute sessions from McMaster University (Little & Gibala, 2010), which gave gains comparable to much longer steady training. Hard, not a sprint: the last one should be as quick as the first. A friendly first interval session.

How to pace it

Hard, but not a sprint: a pace you could hold for a few minutes, run for one. The goal is ten efforts at the same speed. If the first is clearly your fastest, slow it down next week. Keep the easy minute moving so you start each rep warm.

Who it’s for

A good first interval session for newer runners, and a short one for anyone on a busy day: the main set is twenty minutes.

Running it as a group

One-minute changes are easy to miss when every watch beeps at a slightly different time. With one timer for the group, every rep starts together, and a coach can see at a glance who is fading.
