Five Trails Ultra & 3 Trails Half 2026

Five Trails Ultra & 3 Trails Half is a South Downs trail series built around named long-distance paths: the ultra covers 50k across five trails, while the half marathon uses three. The half is 21.3 km, with about 360 metres of climbing and 370 metres of descent, so it is hilly enough to feel like a proper trail run without being a mountain slog. The half marathon runs on trails, footpaths, and tracks, with runnable ground rather than technical terrain throughout. Runners get one aid station and a 5-hour time limit, which leaves room for steadier trail runners as well as faster racers. The event carries ITRA points, a Mountain Level 2 rating, a Finisher Level 220 rating, and a National League rating, and the listed half marathon field is around 350 runners.
