WorldChallenge

Next year I am taking part in the World Challenge expedition that my school has organised to Costa Rica, where a group of us are hoping to make positive contributions to the communities there that need some help. 
I committed to this on the basis that I would raise all of the funds myself (nearly £4,000), and so far have managed to raise half of the money.
Now, with only a few months left to raise the remaining money, I'm starting to struggle. Not only am I revising for my GCSEs which I'll be sitting just before we go, I have also just qualified to trial for the Team GB Rowing squad! Very exciting, but this means more time training to make sure I give myself the best chance at something I've been working so hard towards for the past couple of years. 
Now, I'm asking for some help, please if you can spare just £5 towards my target it would mean such a lot (and maybe you'll get a warm fuzzy feeling when you see me at the Olympics knowing that you helped to get me there :) )
