Overview
Purpose. Sprint while a light elastic cord tows you slightly faster than your own top speed, exposing the nervous system to higher stride frequencies.
How it fits the system. An advanced-level assisted horizontal sprint entry in the Speed & Acceleration section, programmed to develop maximum velocity, neural drive. Related work in the library: Flying Sprint and Wicket Runs.

How to Perform
- Anchor an overspeed cord to a partner or fixed point and stretch it to the prescribed tension.
- Walk back until the cord is loaded, then accelerate normally into the assisted zone.
- Sprint through 20 to 30 metres at controlled overspeed, keeping the mechanics recognisable.
- Decelerate gradually over a long runway and walk back fully.
Coaching Cues
- Assistance should feel like a nudge, not a tow.
- If the feet start slapping or the stride opens up, reduce tension.
- Stay tall through the hips; do not lean into the pull.
- Only run these fully warm and fresh.
Common Mistakes
- Using too much tension, which turns the drill into falling forward.
- Running it late in a session when the legs are tired.
- Using it without an established max-velocity base.
Progressions & Regressions
Progressions
Increase distance slightly before increasing assistance, and alternate with unassisted sprints.
Regressions
Flying Sprint without assistance, or a downhill sprint on a very gentle slope.
When to Use It
When to use
In a speed block, first thing after the warm-up, once or twice per week at most.
When not to use
With beginners, with hamstring history or current soreness, or without a long safe deceleration zone.
Programming
4 to 6 runs of 20 to 30 metres with three to five minutes of recovery.
