The modern pentathlon is one of the most unusual Olympic events.
It’s a single-day competition, with athletes vying against each other in four (not five!) events — fencing, swimming, running/shooting and showjumping.
The "unfamiliar horse ride,” as it is called, is quite an adventure. The athletes draw horses via a lottery, and then have 20 minutes to familiarize themselves with the horses before attempting a 12-obstacle course.
That’s right, the riders attempt to hurdle 12 obstacles on the back of a horse they’ve never met.
“I try to bribe my horses,” Team USA pentathlete Margaux Isaksen told NBC. “Like, I’ll bring small apples or cookies and I try to be really friendly and speak to them like they’re people. It’s a little bit crazy."
A little bit crazy, and a lot more dangerous, as portrayed in the following images from the Rio Olympics.
