There are 2 options, 12hr or 16hr of training per week. If you go onto their website there are options for pretty much every IM race. How specific they are I don't know, hence trying to find out if anyone has used them.
I know a few guys that use Fink and seem to get good results.
Just found out about this race whilst browsing the 70.3 website to decide my races for next season. Thought this would be a real possiblilty, with it just being over a small section of water, but from you have all said, it seems that it could turn out very expensive Had no idea it was so expensive to get a ferry to Ireland! Also with registration apparently opening on 11th October, they are cutting it fine as I haven't found any link to the official website to look at all the race info, routes etc.....??
