So after last Sunday's race, Ironman ditched this 70.3 because they couldn't make enough profit from the 800 entrants. I was gutted because a) I liked the look of the race and had pencilled it in 2013 race calendar. b) I'm quite a big fan of IM brand. Anyway, it turns out Challenge have picked it up and despite having two of my major joints in significant states of disrepair, I've taken the plunge and signed up. Anyone else in? Training tips for swapping minus temperatures in UK for heat and humidity in Thailand, next December, would be greatly appreciated. Although nothing that involved turbos in the sauna, thanks.
