Get your walking shoes on and explore some of the Capital’s less known historic areas with a tour of the ‘gateway to London’ along the Thames’s eastern section. Starting alongside the grandeur of Woolwich Royal Artillery Barracks – we have a NEW 50km looped route, with an Ultra March option for 2025 which heads into the heart of the Capital – alongside the existing 25km option taking in Greenwich – and a NEW 10km option if you’re after something a bit shorter!
WWF is an official Series Partner on all Ultra Challenge treks!
