About the event

Join 2,500 walkers and trek 25km across the Capital with unrivalled views of the skyline and landmarks.

From the start at Putney Bridge, you’ll head east towards the City, zig-zagging over 16 historic bridges, each with its own fascinating story. You’ll finish just beyond the majestic Tower Bridge, where you can celebrate with an afternoon picnic in Southwark Park.

You’ll create memories to last a lifetime and come away with a fantastic sense of achievement. Take on the challenge solo or gather a group of friends or family. With a 10km option also available, there’s a Thames Bridges Trek for everyone!

You’ll get full support all the way, plenty of food and drink, a medal, T-shirt and celebration finish. Push yourself further in 2026, take on an Ultra Challenge and help us drive towards a cure for type 1 diabetes.
