I hiked/ran/cycled 50km of Cairgorm mountain and surrounding area last weekend for Barnardo's. I did it in just over 4 hours and was 3rd. My team was 1st overall (average completion time) and we've thus far raised around £1500 for the charity. Next year DiS should enter a team.

So, which charity event did you partake in over the weekend?
