Ultra Running Race Execution Tools | HARDN

HARDN is the race execution platform built for ultra runners. Real-time pacing, cutoff tracking, nutrition timing, and crew coordination — everything you need to turn months of training into a finish line, not a DNF.

Race day is where ultra runners fall apart

You can have the best base, nail your taper, and show up fit — but without a race execution plan, you're gambling. Most DNFs aren't fitness failures. They're execution failures.

Race Execution Tools

Live tracking with real-time pace and elevation data

Know exactly where you are in your race. HARDN tracks your mile, current pace, elevation, gain/loss, and overall progress.

Aid station timeline with projected arrival times

See every aid station with projected ETAs, crew access points, and drop bag locations. Know how much buffer you have at each cutoff.

Live GPS map with next aid station ETAs

Your crew sees exactly where you are on the course, plus estimated arrival times at the next three aid stations.

Crew instructions that turn anyone into an expert crew

Per-aid-station instructions: what to hand the runner, what to collect, and conditional response guides for common issues.

Real-time communication between runner and crew

Async messaging that syncs when signal is available. No more lost texts or missed calls at 3am.

How HARDN works on race day

  1. Add your race — distance, aid stations, cutoff times, crew access points, or import a GPX file.
  2. Share with your crew — no signup required. Live dashboard with GPS tracking, ETAs, and instructions.
  3. Execute on race day — GPS tracking, pacing math, cutoff tracking, and crew coordination handled automatically.
