This supercharged relay race is like Krypton Factor meets Takeshi’s Castle (Video)

We're out of breath just watching this.

We already know from the likes of Alexis Sanchez, Arturo Vidal and Gary Medel that Chileans are a tough bunch with boundless energy who won't ever give up. But this lot take it to another level. Two super-fit relay teams compete at a startling rate over a merciless obstacle course that requires speed, agility, strength, stamina and balance. It's amazing to witness just how fit and skilled these individuals are. They're actually training for a military pentathlon, so don't feel too bad if it puts your workout circuit to shame. https://www.youtube.com/watch?v=ws_49pzL_QM
