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!

Overview
Head through the Woolwich Tunnel, and north along the ‘Capital Ring’ and ‘Greenway’ to the Olympic Park. It’s down to the Thames via the Lee Valley Walk to Limehouse, past The Tower of London, through the City, and across the Thames at Waterloo Bridge. Back along the Thames – southside – all the way past the Cutty Sark and a rest stop at the Old Naval College. Then along the Thames to the Greenwich Peninsular, past the O2, past the Thames Barrier, through Charlton, and back up to basecamp in Woolwich, where a big cheer, medal, glass of fizz, T-shirts and BBQ meal await!

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.
