I really like to watch swim portion of these races... I think last year they added the number marked on swim caps to help a little bit following the live race... how difficult would it be to have spotters at 500m-1000m-1500m-half-way and 3000m to provide real splits.

I don't want to go the expensive route where the technology already exist to have a full accurate split going under a floating arch,
weather waves, ensuring everyone goes under this tight arch etc... not a good investment and money spent but...

It could be fun to extrapolate the time they would go by these spotters... we would know the gaps, also could calculate the pace, and maybe estimate
completion time of the swim...

Yeah, I know it's too much to ask.. but if we don't it won't happen. Andrew Messick if you reading this... ;)

At least, it would give Michael, Dede and Greg more to speak on the Facebook Ironman now channel during the swim...
