36 hours of running indoors for charity – this is the crazy event that put ultrarunner Krasse Gueorguiev straight into the mainstream media spotlight in Bulgaria. What a twisted experiment – a human-sized hamster wheel equivalent, meant to prove or disprove one thing – the idea that anything’s possible. A special reinforced treadmill tried wearing Krasse down – his shoes, body and mind – but this guy just doesn’t like giving up. He ran well over 200km – all in the same spot, just going on and on and on under the artificial lights while outside day turned into night and then back into day again.
