The AIG just refers you to the website for the maps. No maps were in the guide.
I feel very sorry for the athletes also, because the typical standing order is that it doesn't matter what the officials do etc that may mislead the athlete, the athlete is always responsible as it is their responsibility to know the course. The map on the website which I have copied below, I suspect is what they may have run. If it isn't what they ran, whatever they did run couldn't have been cutting the course unless they started swimming. The official course map doesn't include the course doing the little turnaround at all, it appears to start from the run out at Transition and thenjust do a straight loop in the shortest possible manner. So from what I can see, the leading athletes did know the course and didn't cut it.
But, where it gets interesting, and makes me believe that the 2 lead athletes have a case, is that if you look at my Garmin map below, you can see in the area that is discrepent, the actual course as laid out and run by the balance of the competitors who completed, it's not even the same course as marked, it takes a completely different route and follows the swim exit.
Not that it affects me, and I don't know those who were affected, but it looks to me like the 2 that were disqualified probably shouldn't have been.
