EnduranceLife | Suffolk 2026

Endurancelife Suffolk begins in Dunwich on the East Suffolk coast, offering 10K, half marathon, marathon, and ultra distances on the same day. It is part of the Endurancelife Coastal Trail Series. This particular event is notably flat and fast, differing from many of the organiser’s more hilly trail races. Runners completing any distance gain points for the season leaderboard, making it suitable as an individual coastal run or as part of the series competition. The course crosses protected and managed countryside, including forest tracks, beach sections, a dyke, heathland, villages, nature reserves, and paths near RSPB Minsmere. Organisations such as Natural England, the RSPB, and the National Trust help maintain the area, thus the event emphasizes runners' respect for the landscape. The half marathon commences after the marathon, with the routes converging later, which helps maintain a cohesive field even on the longer distances.
