About this timer

Eight fifteen-second sprints with forty-five seconds to walk back to the line, run twice. The 1:3 work-to-rest ratio is the standard for speed-endurance work: long enough to recover most of your output, short enough that fatigue accumulates across the set. Fifteen seconds is roughly a hundred metres for most people, which is why the walk back doubles neatly as the rest interval.

Best for

  • Any sport with repeated sprint efforts
  • Building speed endurance rather than top speed
  • Track, pitch or treadmill

How to run the set

  • Warm up thoroughly first — at least ten minutes with build-up strides. Cold sprinting is how hamstrings go
  • Mark a line and sprint away from it for the full fifteen seconds
  • Walk back during the forty-five, arriving at the line as the next round starts
  • Set two should be slower than set one. If it is not, set one was not a sprint

Scaling it

Easier
One set of eight, or extend the recovery to ninety seconds and keep the effort maximal.
Harder
Cut the recovery to thirty seconds, or run the sprints uphill.

How the clock runs

One pass through this timer is 16 rounds and 8 min. The sequence repeats 2 times, so the whole session runs 16 min across 32 intervals. The intervals break down as 8 × 45 sec and 8 × 15 sec.

Questions about the Sprint Repeat Drill Template

How far is a fifteen-second sprint?

Eighty to a hundred and twenty metres for most people. Distance is not the point — the fifteen seconds at full effort is.

Should I sprint on a treadmill?

It works, but the belt takes time to reach speed and stopping is awkward. Outdoors on grass or track is better if you have the option.
