SOUNDBITE: (English) Conor Hancock, winner:

"Loved it. Really just a fast course really, apart from not moving my face now...a bit numb. Really cold, some challenging obstacles, really good athletes. Really quick."

Hancock might well have a touch of the obstacle elite about him, but what about the rest? Brave or stupid? You decide..
They braved all sort of obsatcles, over all sorts of terrain. Some suffered in the cold, but most... enjoyed the occasion
