Race Data
Read a race's live positions and station splits
Every runner of a distance as the race's public tracker shows them: status, place, progress, the latest position, the last station report and the splits recorded so far. Bearer key: a Wolfe Run developer key with race:live:read on a race whose organizer turned on open data and companion apps, or the organizer's Endurance HQ API key with race-day:read. Runners the race removed from public view never appear.
Method
GET
Path
/api/public/v1/events/{idOrSlug}/live
Authentication
Bearer key: a Wolfe Run developer key with race:live:read on a race whose organizer turned on companion apps, or the organizer's Endurance HQ API key with race-day:read. Served from https://www.endurancehq.app. Use is subject to the race data terms.
