1300 adventure racers took part in the River Rat Race at the weekend. Billed as London's first ever water obstacle course, the event raised funds for housing and homelessness charity Shelter.
Saturday's event took place over a 10k water course and saw participants run, jump, swim, kayak and climb their way around Docklands in East London.
For each entry, at least £10 was given to the charity Shelter to help people across the country struggling to keep a roof over their heads, with further funds raised for the charity via participant sponsorship.
The race started inside ExCel where participants faced a quick-fire barrage of obstacles before they headed out on to the dockside. From there, they ran west towards the Emirates Air Line, tackling more obstacles as they went before entering the Royal Victoria Dock via a water jump. This was followed by a short swim and then an energy sapping, thigh deep wade on to an urban beach.
Once back on dry land they headed east with a mixture of jumping, swimming and wading before tackling the kayak section and finally the centerpiece obstacle of the event - a towering confidence jump, plummeting them 20 feet into the water below.
Jim Mee, Rat Race Adventure Sports MD and creator of the River Rat Race, said of the event: "It was fantastic to see such a brilliant turn out for our River Rat Race event in The Docklands this year. This is the first year we have hosted the event in the capital and it was great to see everyone getting in to the spirit of it. At 10km, the course provides a good fitness challenge, but the water elements make it a lot of fun, especially when the sun comes out like it did today.
"It has been extremely rewarding teaming up with Shelter for the event and we are pleased that contributions from the ticket sales have helped to raise money for such a worthwhile cause."
Campbell Robb, Shelter's Chief Executive said: "We were thrilled to be part of the incredible River Rat Race that helped raise vital funds for Shelter.
