Live relay tracking

Follow your relay team, live.

Someone on the team shares one link — you open it and watch every split, the live leg, and the whole team's ETA update in real time. No app to install. No account.

From a text message to a live race, in one tap

Spectating is read-only and needs nothing installed. If you can open a link, you can follow the team.

1

A racer shares the link

Anyone on the team taps Share → Watch link. It drops into any messaging app as a normal link.

2

You open it in your browser

No install, no sign-up. The live race loads straight away — on your phone or your laptop.

3

Watch the whole team, live

Splits, the running leg's clock, and each van's ETA update the moment a runner hands off.

The same live view the team sees — read-only

⏱️

Live splits

Every leg's actual time appears the instant it's logged at the exchange.

Each leg's distance and elevation — the hills ahead, at a glance.

Both vans, one view

The team spans two vans; you see across both in real time.

🔒

Look, don't touch

Spectating is strictly read-only — only the team can change anything.

Predict every leg. Time every handoff.

Relay Tracker turns each runner's 10k time into a leg-by-leg plan — pace, finish time, and a running team ETA — and keeps it accurate all day as real splits come in. Built for the 3 a.m. van: big glanceable numbers, and a pace model that still works when the signal doesn't.

  • On-device pace prediction — terrain, heat & fatigue aware, self-calibrating
  • One-tap RUNNER IN handoff — you're always in control
  • Full-fidelity offline — sync van-to-van by QR or Nearby, nothing in the cloud
  • Exchange-approach alerts before your runner is due
  • Course elevation profiles & per-leg route maps
  • Flexible rosters and auto-assigned leg assignments
