Event overview

Starting alongside the grandeur of Woolwich Royal Artillery Barracks (a short walk from the Elizabeth Line, DLR, and Overground) – there is a new marathon looped route for this year which heads into the heart of the capital alongside the existing 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, and capped with a hot meal, bar and music at the finish – making for a wonderful end-of-summer celebration!

A great experience, which I thoroughly enjoyed, already looking to book again!

The whole experience of walking round London but with the sunrise over Tower Bridge was brilliant.
