London Summer Walk

Your Walk – Your Way! 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 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!

The Brain Tumour Charity is an official Series Partner of the 2026 Ultra Series which means you’ll receive a 50% discount on the ‘full sponsorship’ option when signing up.
