I'm pretty sure it's a triathelon. Okay, it's more of an event than a sport. Same thing with British SAS training - although that's brutal, it's not a sport
Mountaineering is pretty demanding. But you can go at your own pace, so maybe it's not as tough, and it also depends on the mountain you're climbing.
I wouldn't pick football, basketball, rugby, American football or tennis, seeing as you can rest at predetermined intervals.
Long distance swimming would be a good candidate. Bicycle riding is also a good candidate, especially in the marathons. But then again, normal marathons are also demanding.
However, I think sprints are the most demanding. If you've ever seen the Olympic 100m sprint, you'll notice that they get very tired very quickly. They're pouring with sweat after running for less than half a minute in some cases.
So yeah, that's what I'm going to go for - olympic running. I would think it's pretty bloody exhausting.
