I'm going to walk with Strider across London during May- National Walking Month- as my contribution to the Great British Walking Challenge (www.livingstreets.org.uk).

Strider is the official mascot of the Living Streets' Walk to School Campaign, and together we will visit every London borough during May- that's on average a different borough every day. There will be a photo from each borough to prove we were there- and we'll hopefully sign up new Living Streets supporters on the way.

We're also going to do a competition to #spotstrider with prizes to be won if you manage to have your photo taken with us!

My target is £500, which will directly support the campaigning work of Living Streets, so please make me and Strider very happy and give generously!
