One of the toughest half marathons in the UK and now the decider of the 2025 Trail Half Marathon World Championship. This iconic course takes on over 1192m of ascent across 21K, most of which is up Wales’ highest peak - Yr Wyddfa (Snowdon). The views are as stunning as the trails are challenging, with those returning fastest in their age division awarded the title of 2025 XTERRA Trail Half Marathon World Champion.

POINTS STRUCTURE AND SERIES RANKINGS
