Now this is something i've never done before but here goes:
Two of my friends are doing the Teide Challenge, which basically involves a 30km ascent of Mt Teide, which is the 3rd highest volcano in the world.
The donations will go towards the Earth Centre Project in Sierra Leone. (With no religious connotations that I am aware of...)
If you have a few pennies that you're willing to send their way, it would be greatly appreciated http://www.justgiving.com/Rachel-Savannah
