Timing multiple runners at once: a track & XC coach's guide

Timing a training group with one stopwatch fails at two moments: the staggered start you can't bookkeep, and the pack finish you can't click fast enough — not because your thumb is slow, but because you're aiming at per-runner buttons. Remove the aiming and one iPhone times the whole group. Here's how that works across a track or cross-country session.

The pack problem

Distance repeats produce exactly the situations that break ordinary stopwatch apps: eight runners on 400s leaving in two waves, a tempo group strung out over 30 seconds, then a finish where four runners cross within two seconds. An app with one button per runner asks you to find and hit the right small target four times in two seconds — while actually watching the finish. Nobody can. The usual fallback is calling times aloud for runners to remember, which means nobody's splits get written down at all.

Starting a session: waves and repeats

In Herotime, runners wait in the order you set. Three gestures on one button cover every start you'll run:

• Rapid tap — a wave leaves as one group, one runner per tap.
• Short tap — the next single runner starts: staggered starts and handicap starts, one tap each.
• Long press — everyone remaining starts at once.

Second wave ten seconds later? Rapid-tap them away too. A latecomer joining rep three? Short tap. The starting order does the bookkeeping; you never choose a name.

Splits, lap after lap

Once the group is running, every tap records the next split, assigned automatically to the least-recently-timed runner — around the group, in order. On repeat 400s that means one tap per runner per lap, in whatever rhythm they cross, and every split lands on the right runner. The record keeps per-split cadence too, so a fading last 100 shows up in the data, not just in your memory.

Pack finishes

Four runners in two seconds is four taps — no aiming, so your taps can keep pace with the line. If two runners have genuinely swapped places since the last split, one drag reassigns the time and the rotation updates itself. (When exact placings in a blanket sprint finish are the point, a camera beats any thumb — our honest comparison says use a photo-finish app for that job.)

Cross country: eyes up at the line

At an XC finish chute you need your eyes on jerseys, not on a screen. The iPhone's physical volume button works as the timing button — a patented part of the method — so you time by feel, calling names while the phone does the recording. It all runs offline, which back-country courses tend to insist on. A neck strap completes the handheld feel.

After the workout

Every runner's series — start, each lap, finish, cadence per split — sits in the timing history when the session ends, and exports as CSV through the iOS Share Sheet. Season-long split trends live in your spreadsheet, not on a clipboard in the rain.
