Sean McColl, writing on his blog:

I knew before this weekend started that it was going to be one of the hardest I’d ever have to endure. To compete in 3 disciplines in one weekend is exhausting. I’ve done it 4 times before, but never in 3 days. Every other time I’ve done 3 disciplines, there’s been a rest day somewhere in the middle; here there was none. A lot of people wonder why I compete in all 3, if I don’t worry about being tired. Honestly, it’s because I love the challenge. Why shouldn’t I be able to do it?

Indeed.
