How it works

You publish splits

You already do this. We need nothing else. Your checkpoint times are all we read.

We build the tracker

We have your race template in the archive. Turnkey. Your logo, your colors, your story.

Runners go live

As you publish splits, every runner appears on a map, with estimated arrival times and a personal link their crew can share.

Families follow along

No login, no app. From the moment you open the tracker, families can watch, leave messages, and sleep knowing where their runner is.

Proof from Badwater 135, 2026

Every figure on this page is counted, not estimated. We parsed our own nginx access log with bots excluded. The numbers are real because they matter to you.

Why other trackers do not work

GPS trackers need GPS

Badwater, Western States, Hardrock and UTMB publish checkpoint times only. Most live trackers simply cannot work without GPS. We turn your splits into live positions instead.

Your race, your name

Not buried in an aggregator. Your race gets its own page, your branding, your story. Families see your race name, not a generic leaderboard.

Replay the year before

Runners use it to train. They see split times from everyone in the archive who ran your course and finished, so they know what a real pace feels like. Enduring traffic.

Talk to us

Tell us about your race. This goes straight to the person who built the site.

No contract. No cost. Happy to run one race for free. If your runners like it, we talk about the next one. If not, you keep your data and we take down the tracker.

About UltraRunTrack

We track 108 races going back 24 years. Badwater, Hardrock, Western States, UTMB, Lavaredo and a hundred smaller races. Every finish time in the archive is replayable, checkpoint by checkpoint, minute by minute.

We built this because split-only races had no tracking at all. GPS got all the attention and all the money. This is the fix.
