AR vs IM vs TdF

came across this interesting look at who is tougher, an adventure racer, ironman triathlete, or tour de france cyclist... an interesting question, with my first half-ironman coming up in just over 2 weeks. i'll let you know what i figure out! (initial thoughts...can't really get into the mind of the tour.... with AR, there are so many things to consider, from multiple disciplines to your unknown surroundings to length of the race, lasting days sometimes... with the IM, the intensity seems unnaturally high for the duration, so that is tough. overall, i'd have to go with AR, although right now the 1/2IM does scare me a bit!
