Inspired by my friend Abi's recent charity drive, me and some of my colleagues have decided to run 100 miles in October for charity. We'd be thrilled if you could donate to a great cause, the charity EMERGENCY. 

I first heard about them from the Vice documentary 'What We're Leaving Behind', where they are providing heroic trauma care in Helmand, Afghanistan. More broadly, EMERGENCY provides free, high-quality healthcare to victims of war, poverty and landmines, alongside building hospitals and training local medical staff. A really good thing.

We'll keep you updated on how it goes, but early indications are a lot of blisters and some surprisingly collaborative comments on each other's running times...
