I am raising money to go to the UK Wild Otter Trust, as otters need our help! They are a threatened species in the UK so I am going to swim 200 lengths which is 5000 metres! Last year I set myself the challenge of swimming 80 lengths for this great cause, but this year I'm going to swim further than I've ever swam before! I hope that you can be persuaded to donate to this brilliant and really important cause!
