Croyde Bay to Land's End in a day, by bicycle. That's the challenge. It's a ridiculously hilly (approx 17,000 ft climbing) 300ish kilometres.

It's the third in a series of linked annual mega-rides that we hope will ultimately take us around the entire British Isles, raising a bunch of cash for a variety of excellent causes in the process.

This year the charity we are supporting is Winston's Wish, set up to help bereaved children who have lost a parent or sibling.

Anything you can give would be hugely appreciated and will help keep me focused when the going gets (and it will - check out the route image) tough - particularly if the predicted 28ºC becomes a reality.

Thank you.
