For broadcasters, watch-along shows and race websites
Hours of live ultra commentary run with no numbers on screen. We track the splits — including at races where no GPS tracker works. Three ways to use them, free, credited, during the launch season.
A broadcast strip for OBS or vMix. Transparent background, refreshes every 30 seconds, never invents a position.
Add a Browser source in OBS, size 1920×160, pointed at:

n = how many leaders to show (1–4).
Finished runners show official chip time; runners on course show confirmed mile and elapsed.

Per runner: status, confirmed mile, elapsed, official rank, splits per checkpoint, projected finish. Positions between checkpoints are estimates and we say so — if you show our numbers, keep that honesty. Field names are stable; if we ever change them we will version the path.
Tell us what you make and we will send the slugs and gun times before each covered race, UTMB week included.
