Soggy socks were par for the course as east Londoners zorbed, waded, kayaked and swam their way around Docklands during the River Rat Race.
The event saw 1,500 competitors brave a 20ft jump into the Royal Docks, a 50ft water slide and a trampoline to raise £40,000 for charity Shelter.
London’s only aquatic obstacle course started at the Excel centre where life jackets were donned before participants plunged into the waters of the Royal Docks to tackle further jumping, wading and energy-sapping challenges on Saturday, July 25.
Rat Race Adventure Sports MD and creator of the River Rat Race Jim Mee said: “We were delighted to be able to bring the event back to the capital this year after our fantastic debut in London last summer.
“Docklands, once again, provided the perfect location for our wet and wild challenge and, as always, it was great to see participants having a fantastic time whilst also raising much needed funds for a charity that helps so many affected by homelessness and poor housing in London.”
