Our 2026 racing season begins on Saturday 14th March at 0900, with the return of the Hundred Hills 50km - now in its fourth year.
You can follow the race live via the tracker here.
Set in the heart of the Chilterns and starting and finishing at Stonor Park, with 500 runners and some truly elite level competition, Hundred Hills has quickly established itself as the spring curtain-raiser to the wider UK season. The format is simple but testing: two distinct 25km loops, approximately 4000ft / 1200m of climbing, five well-stocked aid stations and a 9-hour cut off.
The terrain is classic Chilterns — rolling, never flat for long, predominantly trail with short road links — and the race rewards restraint early and strength late. The first loop can feel controlled and runnable. The second loop often sees the race fragment on the big climb out of Stonor but racing at the front has increasingly been extremely close and exciting.
Stay tuned to our instagram channel too for live udpates and in race content.
The women’s field at Hundred Hills 50km 2026 brings depth, experience and proven ultra strength across 50km to 100 miles. As ever on this course, restraint across the first loop is critical — the second 25km is where the race typically unfolds.
Below are the leading contenders, ordered by current ITRA ranking (highest first).
