London Summer Walk Ultra Challenge

22nd August 2026

Explore the capital with Winston’s Wish!

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 – and fundraise for Winston’s Wish.

Starting alongside the grandeur of Woolwich Barracks (short walk from Elizabeth Line, DLR, & Overground) – there’s a marathon looped route, which heads into the heart of the Capital – alongside a 25km option taking in
Greenwich, and a 10km option if you’re after something a bit shorter! Routes steeped in history with iconic sights, a lively warm up, full support all the way, rest stops with snacks and drinks, and capped with a BBQ meal, bar & music at the finish, making for a wonderful active end of summer celebration!
