Ok, so Ironman is a trademark and longcourse triathlon is a prescribed distance.
Longest day is 15 hours, Mdot is 17 1/2 hours.
There are lots of hills in an mdot, a longcourse can be flat.
Or is it? how much of the above are true?
Isn't there an ironman in Florida (whose topography is similar to wirral, maybe, how do they get the ft climb there?
What are the differences and does it matter?
