Wet and wild was the order of the day as 1,500 participants took to the Royal Victoria Dock for an obstacle course with a difference.
The River Rat Race saw people take on water trampolines, a zorb pool and a 20ft jump off the dock as they charged around the 10km course.
For every person taking part, £10 was donated to homeless charity Shelter, with more funds raised through sponsorship.
Saturday’s event started with a barrage of obstacles inside the ExCel before taking on a swim in the Royal Victoria Dock.
The course also featured a kayak section and a final towering jump.
Creator of the River Rat Race, Jim Mee, said: “We were delighted to be able to bring The River Rat Race 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.”
Shelter’s chief executive Campbell Robb added: “All of the money raised by the incredible runners will allow us to be there for even more families fighting to keep their home.
“Our advisors can make the difference between a family losing their home and keeping it so we’re extremely thankful to everyone who’s taken part.”
While the total amount raised is yet to be confirmed, participants are on track to hit the £40,000 mark to help fund Shelter’s ongoing work.
