Route information

This iconic Olympic venue is where Team GB won Bronze for Rowing in 2012. This flat, manmade venue was built purposely for safe open-water swims and perfectly flat paths for running and cycling.

Each discipline will be accurately marked out with distance markers and arrows to guide you in the right direction and inform you of how far you've come. There will also be marshals stationed throughout the course for safety reasons and of course to cheer you on.
