What This Service Is
UltraRunTrack is a free, independent fan project that displays live race timing and estimated runner positions for select ultramarathons. It is built and operated by Forge Built AI and is not affiliated with or endorsed by any race organiser, race partner, or official timing service.
How Positions Work
Most elite ultramarathons do not provide continuous GPS data. Official timing data comes only from checkpoints that are sometimes 17 to 42 miles apart. Between those checkpoints, UltraRunTrack estimates runner positions using historical pace data for that course section and each runner's recent form.
These estimates are educated guesses. They are not precise. When multiple runners occupy an estimated position, we draw them as a single pack marker rather than inventing separation that we cannot verify.
What These Estimates Are Not Reliable For
Do not use estimated positions to make decisions about crew logistics, medical support, runner safety, pacing strategies, or wagers. The mean error is around 1 mile between checkpoints. Real decisions depend on official timing data from race control or direct communication with the race organiser.
Official Results
Official race results, finishing times, and final placements come only from the race organiser and their official timing partner. For Badwater 135, that is AdventureCORPS and their partner. If you need results you can rely on, go directly to the race website.
Data Ownership
Timing data, race names, course descriptions, and results are the property of the race organiser and the race's official timing partner. UltraRunTrack is an independent display layer on that data and does not claim ownership of any race information.
