As you'll probably know, I lost my brother to CF when he was 13 and I was 7; it's a cause that is incredibly close to my heart. Anything you can give, however modest, will help make a difference.

I'm doing the ride with Rob, an old pal, on a TANDEM - eek. We've had a couple of rehearsals and harmony was maintained, so fingers crossed!

Cystic fibrosis (CF) is a genetic condition which causes sticky mucus to build up in the lungs and digestive system. It affects more than 11,000 people in the UK. One in 25 of us carries the faulty gene that causes it, usually without knowing.
