Want a challenge this Saturday? How about a 15 mile charity walk from Richmond Park along the Thames to Hammersmith? Here's why you should join us:

1) It's for an amazing charity. Maggie’s Centres provide emotional, practical and social support to people with cancer & their families & friends.

2) It's just £35 to sign-up, which you can do online. There's no fundraising commitment, just raise as much as you can.

3) It's a beautiful scenic walk, which will help you to burn calories & get fit.

4) I will be doing the warm-up at the start!

Go to the Maggies website for more info & to sign-up. Hope to see you there!
