The Rat Race is a mental and physical adventure challenge that uses the cityscape as its playground over a whole weekend. Teams of three have to run, climb, mountain bike, abseil and kayak the streets, structures, waterways and urban jungles as they navigate their way around a course that's only revealed hours before they begin.

Add Momentum have three teams taking place in the race, most of whom are really quite scared about how much running there is involved! We have set ourselves the hard target of raising £10,000. So please, if you can give generously.

Many thanks for your support.
