How to run it
Warm up for 10 minutes, then run 8 x 400m at mile pace with 1 min of walking after each, and cool down for 10. Aim for even reps rather than a fast first one; the last should feel hard but in control.
What it's for
Short reps at mile pace train speed and running economy: quick turnover and good form at a pace faster than you race most distances, so race pace feels easier.
