It sounds simple: run three miles and then run one mile every hour for 24 hours until you run a marathon. It sounds so simple that maybe you should make it more complicated. How about running one mile every hour and also build a table, some oars, clear all the rubbish along the way you run and maybe 30 odd other household tasks. Why not try and do as much as you can in 24 hours? And run a marathon?

If you like the sound of simple ideas that clearly collapse when you get to around hour 20, mile 20 and you’re utterly knackered then this is the video for you. Optimism, idealism and a healthy dose of stupidity. But such a simple idea that you think: “maybe I should give it a go too?”
