South Downs Ultramarathon 2026

The South Downs National Park defines this race: chalk cliffs, green valleys, villages, and the South Downs Way underfoot. The South Downs Ultramarathon is a trail event for ultra runners who know that scenic country can be challenging, with seaside air, wooded sections, and open downland included. Expect classic South Downs Way trails, wide chalk paths, technical descents, and climbs that test you after the initial excitement fades. The reward is not ease, but striking landscapes and broad views of the coast, the kind earned on tired legs among those who came for the same demanding challenge.
