Both vans, one race clock. Predicted splits for every leg, one-tap handoffs, and a live link your fans can follow — with a pace model that works when the signal doesn't. 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, 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 nam-only. • Or stay fully offline: sync van-to-van by QR code, 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 alerts a few minutes before your runner is due at the next exchange — scheduled from the predicted clock, on your device. • 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 fve. • Auto-assign leg assignments, or set them yourself. • Light and dark themes; big, glanceable numbers for tired crews in a moving van. No ads. No tracking. No account needed. Plan offline and nothing leaves your phone; in a team, Relay Tracker syncs your race data so everyone can follow along.
