In September, my wife and I had the “pleasure” of doing a half Ironman relay in western Washington state.
My wife did the swimming and the running, and I did the biking. Most of our friends say I did the easiest part. In my defense, I would point out that the bike is the longest portion of the triathlon (56 miles). Plus, I had to worry about getting a flat, and several times I had to make the agonizing decision as to whether to pass other cyclists. Exhausting! (mentally, at least)
