Eryri National Park in Snowdonia, northern Wales, has been selected as the host venue for the 2025 XTERRA Trail Run World Championship, taking place next year on July 12-13.
The off-road competition will unite trail runners qualified through XTERRA Trail Run World Series events worldwide, competing in the Trail Marathon and Half Marathon distances for a US$10,000 prize purse and the title of 2025 XTERRA Trail Run World Champion.
This will mark the 16th annual XTERRA Trail Run World Championship. XTERRA adds that the weekend-long festival will not only feature competitive races but will also include a series of community and family-oriented activities. The event aims to provide an inclusive experience that celebrates trail running, community engagement, and the host location.
XTERRA Snowdonia Eryri, a trail running festival in Llanberis, Wales, has been a key XTERRA event for three years and a highlight of the XTERRA Trail Run World Series. Now entering its fourth year, the continued partnership with local organizer Always Aim High Events will climax XTERRA’s 2025 trail running season.
- Half Marathon (21K): Starting and finishing in the Welsh village of Llanberis, the Half Marathon features over 1,192m of ascent, largely concentrated on Wales’ highest peak, Yr Wyddfa (Mt Snowdon).
- Trail Marathon (44K): This features a 1,685m of ascent, circling and summiting Yr Wyddfa (Mt Snowdon).
