Oh, that's right, tri athletes (which Ironmen are) are regarded with sneering disdain here.
I would expect that most triathletes are going to go a little harder on the run as it's the last segment. It's also more difficult to take in and digest nutrition while running.
I don't think many tri athletes do many, if any, 26 mile training runs, whereas it wouldn't be uncommon to do 180km bike rides.
