How does one prepare for an event if you don't understand the demands of the event?
Fergie, a few years back they changed the start for the pros to 15 then 30 minutes ahead of the age groupers. This was because the better women swimmers thought it was "unfair" that the slower women pros in the swim could get a draft off of the fast age-group men on the bike. Plus some of the women were getting beat to a pulp by some of the more aggressive age-group men trying to get the glory of being first out of the water.
On multi-loop courses (Kona is not a multi-loop course) it also affects all the pros as they find themselves having to weave through slower bikers and runners later in the race.
Anyhow, Ironman triathlon has traditionally raced men and women together (ITU is a different story) on the same course and same time as the age-groupers. So, a WR is what they say it is, not what you think it should be.
