Analyze sprints with Sprint Insights
Read an athlete’s times on every stretch of track, compare runs gate by gate, and check how steady they are across repeats.
Sprint Insights read one athlete’s timed sprints from the Timing Gates. Open Labs → Insights → Sprint, pick the athlete, and set the Period. There is no exercise to choose: every linear sprint counts, and you can filter by exercise. Change-of-direction drills (505 Agility, Pro Agility, L-Drill, T-Test) are left out.
| Tab | Question |
|---|---|
| Track segments | How does the athlete do on each stretch of track? |
| Compare runs | What changed between these runs? |
| Repeatability | Does the athlete hold the time within a session? |
Sprint times are shown in seconds with two decimals.
Stretches: how runs are compared
A stretch is a range of track between two gates, counted from where the athlete set off. A 10 m lap after a 10 m run-in is 10–20 m, the same as the second lap of a 0–10–20 m run, so different gate layouts are compared fairly.
Loaded runs are kept apart: loads are grouped in 5 kg bands, and a sled or vest run is a different stretch from a free run (for example “0–10 m · 20 kg”).
Shared settings
These hold across the three tabs:
- Stretch: every stretch measured under the current filters, with its number of runs. The most-trained one is chosen by default.
- Load: Any load (default), Unloaded, or a specific load. Shown only when more than one load exists.
- Exercises: restrict to some sprint exercises. Shown only when there are several.
- Restore default values resets these (not the period).
Track segments
Choose Session read by: Best run (default) or Median run.
- Tiles: Best in the period (fastest time on the stretch, with its date), Typical session (the median of each session’s best or median run), Last session, and Sessions (with the number of runs).
- Timeline: one point per session. The solid line is each session’s best run, the dashed line its median run, and the grey band runs from its slowest to its fastest run. Lower is better. The table lists each session’s runs, best, median, range, and loads.
- Every stretch measured: all stretches with their load, runs, sessions, best, median, last, and exercises. Select Read to switch the board to that stretch.
Compare runs
Compare two to six runs over the chosen stretch.
- Choose the Stretch.
- In Runs over the stretch, tick the runs to compare. Runs are grouped by session, newest first, each with its time over the stretch. Clear unticks them all. Your picks are remembered per athlete.
The comparison uses the gates all picked runs share inside the stretch:
- Split curve: cumulative time at each shared gate, one line per run.
- Speed per split: the average speed over each split, one bar per run.
- Splits: each split’s time, plus the whole stretch. From the second run on, Δ vs first shows the difference from the first run you picked: negative (green) is faster.
“Pick at least two runs” means fewer than two are ticked.
Repeatability
How steady the athlete is across repeats of the stretch within each session.
| Measure | Meaning |
|---|---|
| CV | How much the runs varied (standard deviation as a % of the mean). Lower is steadier. Needs two runs. |
| Gap | How far the typical (median) run was behind the best, in %. |
| Decrement | How far the average run was behind the best, in %. Needs three runs. |
| Rest | Median time between consecutive runs on this stretch. Other drills done in between count toward it. |
- By session: one bar per session for its CV, with a line for its gap. Click a bar to read that session below.
- Session of a date: each run in order against the session’s best, with tiles for Best run, Median run, Variation, and Rest between runs. The best run is green; the others show how far behind it they were.
Empty states
- No sprints in the period: widen the period. Runs need timing-gate laps and a finished, uploaded workout.
- No stretch under these filters: widen the Load or Exercises filters.
