How to run it
Warm up for 10 minutes, then run 5 x 1.6 km at threshold pace with 90s of easy jogging 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
Long reps at threshold pace raise the pace you can hold before fatigue builds quickly, with short breaks so you can do more of it.
