Take on the Thames Twilight 10 on Friday 10 September 2027.

With The Oval cricket ground as the start and finish venue, experience London in a different light, passing famous landmarks, including St Paul’s Cathedral, Westminster Abbey, Tower Bridge, and the London Eye.

Sign up as an individual or as a team and get full support all the way. All routes are fully marked, and you'll receive a special t-shirt and well-deserved hot meal at the finish line.
