Find The Perfect Ultra-Marathon Race in the UK and Beyond
Finding the perfect ultra shouldn't be harder than the race itself. Most race calendars only give you a date and a location and are built for race directors, not runners.
But as trail runners, we know that a "100km in May" could mean a flat canal path or a 6,000m mountain grind. That’s why we built the findtrail.co/race Race Finder, the UK’s most detailed database for endurance athletes looking for ultra-marathon races.
Use our filters to find exactly what you’re looking for:
By the Numbers: Filter by distance, total elevation, or "m/km" steepness.
By the Season: Find your perfect spring warm-up or a gritty winter expedition.
By the Map: Search every corner of Wales (complete database) and across England and Scotland (growing daily!).
By the Vibe: Toggle between fully-marked trail festivals and self-navigated mountain loops.
