Endurancelife Sussex
Eastbourne, United Kingdom · Saturday 6 March 2027
The Endurancelife Sussex Marathon is a hilly 42.2km trail race across the South Downs near Eastbourne, with over 1000 metres of elevation gain that will test your legs from start to finish. Taking place in March 2027, it's part of the broader Endurancelife season, so your performance here will earn you points toward the overall leaderboard if you're chasing competitive recognition. The route makes East Dean village a particularly good spectator spot, so if you want supporters on the course it's worth directing them there. Accommodation is plentiful in Eastbourne itself, though the organisers specifically recommend staying in East Dean if you're making a weekend of it. This is a proper hill runner's race on technical terrain, not a fast road marathon, so prepare accordingly with trail-specific training and expect a long day in the field.
