XTERRA Trail Run World Series

The XTERRA Trail Run World Series is an inclusive series that invites all trail enthusiasts to join the XTERRA community as we connect, explore, and discover new and existing trails in idyllic running terrains the world over.

Designed to mix community and adventure, the series is open to all runners, from amateur to elite, individuals and pairs, with over 30 races in 20+ countries across Europe, the Americas, and the Asia-Pacific region.

Compete individually, regionally or globally in the XTERRA Trail Run rankings, or push to the front of the pack in your age group to qualify for a place on the starting line at the annual and invite-only XTERRA Trail Run World Championship.

Distances & Categories

The XTERRA Trail Run World Series includes both half-marathon (15-34km) and full-marathon (35km+) races, with individual and team (duo) categories available.

But racing duos who choose to suffer together must also finish together in order to be awarded points and Trail Run World Championship slots.

Slots awarded for full-marathon and half-marathon races are only valid for Championship races of the same distance category. However, those who have qualified for the half-marathon World Championship race may apply for the full-distance race in cases where a full-marathon race was not available within the region.
