Video: You’ve Never Seen an Obstacle Course Race Like This One

If you're an obstacle course racer who has already done all of the major events, perhaps you need to put Red Bull's Conquer the Castle on your schedule. This wild competition sends athletes to Rosenholm Castle in Denmark to take on a series of increasingly difficult challenges that are straight out of Medieval times. The course itself is just 4 km (2.4 miles) in length but it features 20 obstacles to overcome, and as you'll see in the video above each is more nefarious than the last.
