According to multisports.com you can

still register for sold out, filled up ironmans (placid, canada) if you buy their training packages…1600.00…guess there really is no such thing as a full race.

Whoa, are you kidding me? Is this real?

i took the registration all the way up to submitting credit card info and the website never stopped me or indicated i still couldnt enter…honestly i would rather see someone buy a charity slot for a grand…

I did their IMFL camp last year which included entry (I was desperate having missed IM Canada due to injury), 3 day camp, and online training program incl Q&A from Roche and Huddle. Camp was well done with Huddle, Paula, and the rest of the MS gang. Did a long swim and short run one day, Biked the course one day with transition run, and ran one loop of course (13.1 miles) on final day. Mixed in were some pretty informative (and funny) sessions on all types of related topics. Bonus was meeting a lot of cool triathletes from around the country.
