If its not full distance its not an IM. Still possible the swim is cancelled too. I tried to get a deferral to next year but was told I was outside of the 45 day period - how the hell could I have predicted this! Section 9 of online waiver states IM can amend or cancel event WITHOUT COMPENSATION! Looking at Consumer Rights Act 2015 contract 'fairness test'. Won't go anywhere near IM in the future. No sporting ethos about them just a big ugly business. Look elsewhere and support grass routes event from now on.
