In October 2010, Jim and Ollie will set a unique record - by passing a rugby ball as many times as possible as they climb Mount Kilimanjaro - the Sunshine Mountain - a 19,330 ft hike.
They are doing this to raise money for two charities, the TAG Rugby Development trust and Water Aid, as well as for the sheer endeavour of pushing themselves to the limit.
Everyone who supports Jim and Ollie and donates to one of these causes is invited to guess the total number of passes thay make. Check recent guesses here. The closest guess will receive a Gilbert rugby ball from the RFU signed by the England Team and the next closest will receive a shirt signed by the London Irish team.
