That was possibly one of the worst written articles I've ever read. Don't get me wrong, I love riding more than anything in this world but I would put the following before equestrian in terms of difficulty:
- Modern Pentathlon.
How many top equestrian riders would have the endurance for a triathlon? I would bet a substantial amount of money that most members of the Olympic equestrian teams wouldn't be able to finish a triathlon within an acceptable amount of time. Of course most people who ride are going to think it's the hardest sport but outsiders would never see it that way, and I would have to agree with them. It's hard just not triathlon hard. :)
