Relay Tracker

Relay Tracker helps relay teams know exactly when each runner will finish — and when Van 1 needs to hand off to Van 2 — with live tracking both vans and your fans can follow, plus a pace model that still works when the signal doesn't. Built for long-distance, multi-leg road relays — the overnight, two-van, 200-mile kind — Relay Tracker turns each runner's 10k time into a leg-by-leg race plan and keeps it accurate all day as real splits come in. Pick your race and the app loads every leg's distance, elevation profile and weather forecast. Enter each runner's 10k time and Relay Tracker predicts every leg: pace, finish time, and a running race-clock ETA for the whole team. Predictions adapt to terrain, heat, and fatigue across a runner's 1st, 2nd and 3rd legs — and self-correct from each runner's actual splits. LIVE TEAM TRACKING • Create a team and share an invite code — both vans see each other's splits in real time, right after every exchange. • Fans can look your team up by name and follow along live, read-only. • Or stay fully offline: sync van-to-van by QR or Nearby, with nothing in the cloud. Cloud sync has an off switch. RACE DAY • Live runner timer with a clear one-tap "RUNNER IN" handoff. You're always in control — nothing auto-advances — and any logged split can be corrected later. • Optional on-device alerts a few minutes before your runner is due at the next exchange — scheduled from the predicted clock; nothing leaves your phone. • Works when the signal drops — race data and forecasts download ahead of time. PLAN THE WHOLE RACE • Every leg's predicted split, plus your total finish window. • Course elevation profile and per-leg terrain — the hills ahead at a glance. • Flexible roster — as many or as few runners as you actually have. • Auto-assign leg assignments, or set them yourself. • Light & dark themes; big, glanceable numbers for tired crews in a moving van. No ads. No tracking. No account needed. Play offline and nothing leaves your phone; in a team, Relay Tracker syncs your race data so everyone can follow along.
