Let’s go to Wikipedia to understand what modern pentathlon is about :
The modern pentathlon is an Olympic sport that comprises five events: fencing, 200 m freestyle swimming, show jumping, and a final combined event of pistol shooting, and a 3200 m cross-country run. The sport has been a core sport of the Olympic Games since 1912, and since 1949 an annual World Championship has been held.
The original idea was to make a sport for the “perfect gentlemen” of the early 20th century, able to shoot a pistol as well as ride a horse or run a few kilometers.
Now what’s so bad about it?
Well if you’ve ever catch the modern pentathlon retransmission during the Olympics, you can say that most of the competitors are very good runners and swimmers, and good enough fencers and shooters.
But the problem is that 98% of them are terrible riders. But yet, they go on a 1m to 1,25m show jumping course with a horse they only met 20 minutes before.
Yes, they don’t know the horses, because they borrow a bunch of horses and there is a draw to determine who rides who. Let’s see what Wiki says about this:
The riding discipline involves show jumping over a 350–450 m course with 12 to 15 obstacles. Competitors are paired with horses in a draw 20 minutes before the start of the event. This unusual skill - the riding of a horse that is previously unknown to the rider - is unique in the world of sport and is one of the elements which gives Modern Pentathlon its special character.
I call bullshit. As you can expect, the result of such a format is catastrophic. Here is some Google image results.
Now I’m wondering who the hell lend their horse to a pentathlon competition??
