I'm taking a brief break from the marathon training to join the Acer UK team to go full (not full) Bear Grylls to try and walk, swim, kayak and maybe run my way through the five largest Isles of Scilly.

It's all in support for the RNLI, the Royal National Lifeboat Institution, a charity that saves lives at sea.

If you're feeling generous and can spare pounds, Euros, dollars and any other valuable currency, all donations will be greatly appreciated.
