The weekend also includes a separate 25 km Thames Bridges Trek and the Moonlight 10 Walk through central London as part of the festival programme.
Support and logistics are provided along the route. Covered rest stops appear approximately every 12.5 km with major stops about every 25 km; catering includes snacks at shorter intervals and meals at longer intervals, with dietary requirements catered for. The route is signed with arrows and glow-sticks where needed, and a GPS tracking app records progress. Timing checkpoints scan participants at rest stops and progress is monitored by a control room.
