A couple of weeks ago, nearly 1500 competitors (as well as their friends and family) from around the world flew out to the Nevada Desert to take part in one of the world’s hardest endurance races. The participants and their pit crews descended on Lake Las Vegas for the weekend, with World’s Toughest Mudder, a 24 hour obstacle race, being the centre of their weekend. This year, as well as the thousands in attendance, almost a million extra people from 200 countries watched the action online.

Some of the people who run this race are experienced athletes who live and breathe for these serious challenges. Others are just normal guys off the street, doing this with their mates, some for fun and others for charity. Before they put themselves through 24 hours of pain, we spoke to some of the competitors who'd flown halfway around the world to take part.
