Get ready to swim, wade, crawl, climb, jump, splash and run your way around our aquatic obstacle course. Brought to you by Rat Race, this is your chance to join 1,000s of #RatRacers at London’s ExCel centre for this wet ‘n’ wild 10km running course around Docklands, linking together many special water and shore based activities. Whether you do it solo, or form a team, all you need to take part is a pair of trainers and a sense of adventure.
