Questions about 17k events worldwide
What should I check before a running event in World?
Choose your distance, then check the route, elevation, cut-off time and entry conditions in the organiser’s race guide.
Which 17k events are coming up in the world?
Retie Trail is listed for 25 October 2026. The Maverick Dark Oxfordshire Trail 2026 is listed for 7 November 2026. Red Rock Canyon Ultra is listed for 14 November 2026. Check the race guide and organiser’s latest information before making plans.
Where can I find race entry details for the world?
Follow the link from the race guide to the organiser or entry provider, where one is available. Check the entry deadline, eligibility and current availability there. A listed race date does not necessarily mean entries are still open.
Why has a race moved out of the upcoming calendar?
Once its listed dates have passed, a race moves to the past-editions view unless another upcoming edition is recorded. Cancelled events also leave the upcoming list. The race guide stays available, and the event returns when a new date is added.
