Race guide

Garmin Epic Trail’s mountain route and conflicting finish times

This is a technical mountain marathon around the edge of the national-park landscape. The advertised 5,600 metres of combined climbing and descending is not 5,600 metres of ascent. Prepare for the stated uphill load and sustained descents instead of transferring a road-marathon pace target.

The cutoff table and programme must be reconciled before you rely on the later finishing time. The page also lists intermediate gates at Bony de la Cabanera, Boí Taüll station, Pont de Sant Martí and Taüll. Obtain the final participant guide and evaluate every gate; an overall finish estimate cannot replace those checks.

Collection is listed for Friday, June 18 from noon to 20:00 and Saturday from 06:15 to 07:00. The race starts at 07:30, so choose a collection plan that leaves time for required equipment checks and reaching the line. The festival spans three days, but the marathon is specifically the Saturday race.

Read the current mandatory-kit list and map before choosing a pack, clothing and carrying capacity. Mountain weather and terrain can change the time between aid points, so practise using your equipment and familiar supplies on comparable outings. Confirm permitted support locations rather than asking companions to meet you on sensitive or inaccessible mountain paths. The entry limit and advertised registration do not guarantee a place; retain your own confirmation. A road-marathon training calendar can organize weeks, but it does not by itself prepare you for this course’s climbing, descending and technical footing. Recheck the final safety briefing and follow any weather-related route changes issued by the organizer.
