Join team brainstrust’s mission to help people with a brain tumour at the fantastic Challenge London Tri. This event is all about choice. Will you choose the Olympic, Sprint, Super Sprint or new middle distance event? The swim will take place in the sheltered Royal Victoria Dock while the bike route will take athletes from Docklands to Westminster and back, taking in some of London’s most memorable sights along closed-roads, while the multi-lap run will take place within Docklands, perfect for spectator support. This is the worlds biggest city centre triathlon. Registration closes on 21st June 2024.
