I was there this weekend. Firstly the pre race swim chute was packed...no distancing whatsoever (with the exception of the very front, sub 27 min people). So, if that’s the reason for no swim warmup, then it didn’t work.
There was a place to the right of the start that easily could have been a warmup area. For some reason they didn’t allow people to swim there on Friday or Saturday but was fine Thursday. Made no sense, they had no lifeguards on Thursday and could have easily had several on Saturday.
The real logistical challenge was getting from there to the swim chute. With the pros exiting and hoping on their bikes by 7:25 or so, everyone would need to be leaving the water by 7:10 latest to get safely across the first part of the bike course and then do the long walk around to swim start...challenging but maybe doable, especially since it look at least 45 minutes to get everyone in the water.
Alternatively, they could flip the start and go in on the right and exit on the left (facing the water) and have the swim start chute go off to the right down the hill...this would have allowed for free and easy warmups. IMO....
I’m no expert, and IM is, but I do think every effort should be made to allow in water warmups, especially in big crowded races with cold water...
