135 miles from the lowest point in North America to the Mt. Whitney portal. In July. The cutoff is 48 hours and nobody out there is carrying a GPS unit, so we read the official splits and put every runner on the course, mile by mile. Not just the front.
Badwater, Hardrock and Western States carry no trackers. No units, no beacons, nothing to charge at mile 90 — every GPS tracker on the market is useless at exactly the races people most want to watch.
We read the splits instead. That is why these races are here and nowhere else.
Nobody has ever been able to look at that. Put any two runners side by side across every race they have both started. Compare two runners.
Pick a target finish time and see the real cumulative split at every checkpoint from everyone in our archive who ran it. Median and the middle-half spread, on the exact course layout you will race. No model, no advice, just what they did.
Ultra fans do not skim. During a race they sit on one page for hours, refreshing to see whether one specific person is still moving. It is a small, fanatical, hard to reach audience, and it arrives on its own.
Most of these races have no GPS on the runners. The only truth is the time each athlete crosses a checkpoint. We take those official splits and estimate position between stations using the field's real historical pace for that exact stretch of course, adjusted for how each runner is actually moving on the day.
A runner is never shown past a checkpoint they have not reached. If they are overdue, they hold at that checkpoint and get flagged, so the map never invents progress that did not happen.
Every runner has a shareable link, an estimated arrival time at their next checkpoint, and their full race history. Follow anyone with a star and they stay pinned on your map.
Slept through the night? Drag the scrubber back and watch it from the gun. These races run 48 hours. Nobody watches all of it live, including us.
One email per race, when tracking opens. Nothing else, and one click to stop.
If your timing publishes checkpoint splits, we can track it. No GPS units, nothing to install, nothing to pay, now or later. Your runners get live positions, their crews get a page telling them where to be next, and their families get to leave a message that gets read out at the next aid station.
