I'm entertaining the idea of doing an Ironman or 1/2 next year. I've done a few Xterra tris and one Sprint triathlon. I've run a marathon, several half marathons, a 25k, did a 5 mile open water swim (I don't know why, it just sort of happened). Anyways, I'm looking for the next challenge.
I'm just wondering how much the registration fee is usually and how early I need to sign up?
Also, about how many months of dedicated training?
Thank you!
