Agility turns
How Metric Sprint judges whether a foot reached the turn line, when it asks you to review a turn, and how to check turns after a session.
Metric Sprint watches every turn in a 5-0-5 or a 5-10-5. Sprint asks you about only the turns it cannot call itself. On these tests the whole result hinges on whether the foot actually reached the line.
That call is the hardest thing to judge from the sideline. In a setup that only measures at the gates, it is also the easiest corner to cut. An athlete cuts it when they run hard and chase the best possible time.
How Sprint judges a turn
Each turn lands in one of three buckets.
- Confirmed automatically — the foot is clearly at or past the line, and the ankle tracked cleanly. Sprint saves the run without interrupting you. Most turns land here.
- Close call — the foot is close to the line, and Sprint cannot be certain either way. Sprint flags the turn.
- Line not reached — the foot is clearly short of the line. Sprint flags the turn.
Review a flagged turn
When Sprint flags a turn, Sprint holds the result before it saves the run. Sprint then opens the review. The review shows a zoomed, scrubbable clip of the turn. Sprint draws the turn line on the ground in perspective, so you judge the plant against the real line instead of eyeballing it.
- Scrub to the moment the foot plants.
- Judge the plant against the drawn line.
- Tap Confirm turn to save the run.
- Tap Reject & re-run to throw the run out instead.
Reject & re-run throws the run out completely. Metric writes nothing to your history. A short turn cannot quietly become a personal best.
If a run has more than one flagged turn, Sprint steps you through them one at a time.
Review turns after a session
Saved runs keep their footage.
- Open the set from your history.
- Find the Legs card.
- Tap Review turns.
The button reopens the same scrubber, read-only. You step back through what Sprint confirmed and why. Each turn shows how Sprint judged it: auto-confirmed, confirmed on review, or line not reached.
Use this when an athlete queries a time. Use it also to check a whole session of turns together after the fact. This is an alternative to checking one turn at a time on the field.
Why Sprint checks the turn
A short turn is a faster time, every time. Timing gates cannot see a short turn. A coach with a stopwatch on the sideline rarely can either. You judge the plant against a drawn line instead. That is about as close as you get to an honest change-of-direction number without a force plate under the turn.
