Shit a brick, I can only do 1000-odd in 5 minutes Fair play Martin

I'm going to get my mate to try this, he holds (probably held by now) the record at a gym in Morecambe for distance in 40 minutes continuous, spent days on it I've never asked him before, due to the blatent humiliation factor...

Edit : on 8, I can do 500m in 1:51, but no way keep it up
