Triple Olympic distance? Hmmmm. Intriguing. Even the swim?
That's longer than an IM. Which is fine with me.
The swim is 4000m compared to the IM 3800m. Per ITU announcement on 2015 World LC: "Event organisers have proposed a 2-lap 4km swim, 3-lap 120km bike, and 3-lap 30km course for the 21st edition of one of the most grueling events on the ITU schedule."
However, I did ITU World LC (Triple O) in Holland back in 2008 and we went well past 4K...something like 2.8 miles. The bike and run were on target. Regardless, the Triple O definitely favors swimmers and the training is closer to an IM than a HIM.
