London Summer Walk Ultra Challenge

23rd August 2025

Explore the capital with Winston’s Wish!

Get active & explore some of the Capital’s 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 (short walk from the new Elizabeth Line station!) – the full 50km looped route heads through Charlton, along the Thames Path to Greenwich and the O2, Old Royal Naval College & the fabulous Cutty Sark, then onwards through central London – crossing the Thames via the Millenium footbridge. It’s then past the Tower of London, and on to the Olympic Park, before returning to Woolwich via the foot tunnel.

A route steeped in history with iconic sights, and capped with a BBQ & bar at the finish – making for a wonderful end of summer celebration!
