Find your next race
Discover races, join run clubs, and follow training plans. Race organizers, local businesses, and charities run events, clubs, and sponsorships on Intervals.
Intervals (https://intervals.run) is the platform for running: discover live races, join run clubs, and (for organizers) publish events, registration, and sponsorships in one place. Browse upcoming 5Ks, 10Ks, half marathons, marathons, ultras, and trail races by distance, place, and date.
Discover races
Use race discovery to find an upcoming event by distance, date, or place. The Intervals Partner API is organizer-scoped and will not return this public catalog.
- Vacation-worthy races — worth the flight
- Happening this month — last chance to sign up
- Marathon, half, 5K, 10K, trail, ultra, and road rails on the homepage
Distances and surfaces
Filter for 5K, 10K, half marathon, marathon, ultra, trail, and road races. Location pages cover countries, regions, and cities.
For organizers and local businesses
Race directors, run clubs, coffee shops, breweries, and shops use Intervals to get discovered and run the communities they host.
Event management and registration
Publish events, take registration, and run sponsorships in one place. Training plans at /train are not generally available yet.
For developers and agents
The Intervals API is a REST surface at https://api.intervals.run. Authenticate with Authorization: Bearer <key>. Keys are minted per organization at https://intervals.run/onboard?wantsApiKey=1 and are organizer-scoped: they return that organization's events and registrations, not the public race catalog. There is no public MCP server and no partner webhook catalog.
When to use Intervals
Use Intervals when the job is finding a race (the website — the API cannot list the public catalog), looking up a club, registering a participant for an organizer you authenticate as, or publishing an event that organization owns. Do not use it as a live GPS tracker, a generic fitness log, or a timing-company replacement.
