I was gonna post this as a reply under the "future of triathlon," but hopefully that thread is dead.
So....first of all does anyone have any real stats on the benefits of swim drafting and bike drafting? It seems to me that the coefficient of drag in the water is HUGE compared to air, even at speeds as slow as 4mph.
Second, I think the only reason why the drafting in swimming is a small advantage is that the swim leg is so short compared to the bike. Which leads me to.....
I just find it hard to believe that cyclists can find anything to complain about when a triathlon is almost always at least 50% cycling, 30%running, and at most 20% swimming. The normal argument is that if the disciplines were equal-timed there would be a disproportionate amount of energy used in the swim. But, I swear someone on the "future of triathlon" thread said that a 6-7 mile time trial on the bike is as hard as a draft-legal hour long race. If a 6-7 mile time trial is so tough, then why would a race that was 1mi swim (WR 14:3~), 7.5 mi bike, 5K run be so unfair?
As for the post about draft legal ironman, that will never happen, and I was definitely talking about 1:45min in an Olympic Distance. Drafting for 2.4 miles in a pack at Ironman, if done right, would probably save 5 minutes. But, the swim at Ironman doesn't even matter at the elite level. Everyone swims under an hour, most pros more like 50-52min. To train to swim under 45 minutes is a waste of time (60K+/week), when a triathlete with a strong swimming background can swim once a week and go 51.
