Just received the email that St Polten is under the Challenge umbrella on the same day as the new Graz 70.3.
I got that as well, I think it was a rallying call to avoid low numbers as I think a lot of people will go for the Ironman brand and new course.
I’d like to do both and just before my 50th but an expensive trip to America will probably stop that.

Yeah, knew about the ‘brand change’ for St Polten. The fantastic swim & bike courses at StP are well documented here on TT. Shameless date selection by WTC 
I would have liked to do it again, in 2013 they cancelled the swim as the air temperature had dropped significantly with a cold front
