This will be my first sponsored running event. But it's a run with a difference. The 5km race is unique in that  runners can choose to undertake some or all of the run  blindfolded while being led by a non-blindfolded partner. So I hope to run at least some of the route without vision.

It takes place on 14th September in Victoria Park, London and is to benefit Sense - hence the blindfolded element to the run.

Donating through Justgiving is quick, easy and totally secure. It’s also the most efficient way to sponsor me: Sense - National Deafblind and Rubella Association gets your money faster and, if you’re a UK taxpayer, Justgiving makes sure 25% in Gift Aid, plus a 3% supplement, are added to your donation.

So please sponsor me now!

PS I'm also doing a half-marathon to benefit the Bone Cancer Research Trust in October - in memory of my son Martin - if you prefer to sponsor me on that. Martin died last year at the age of 17 after a year of treatment for bone cancer. See http://www.justgiving.com/malcmatthews
