On 2 and 3 June the world's first 'RunHack' was organized in London. In the presence of 50 other running enthusiasts, divergent ideas were formed over the course of two days about how we should shape 'the running-friendly city' of London. We ourselves did a short study into the behavior of 'run-commuters' in London, an ever-growing phenomenon. The goal is to organize a first RunHack in the Netherlands in the future, follow the developments via @RunningHack and #runhack!
