I've foolishly signed up for the ÖTILLÖ Sprint Final 15K, a swimming and running race around the Swedish island of Utö in three week's time. I'm not a great swimmer, and haven't done a lot of trail running. But what could go wrong? 

I'm using this as an opportunity to raise money for the Human Dignity Trust, a charity which uses the law  to defend the human rights of LGBT people globally. Your support would be much appreciated.
