This was reported this morning and RIP to the two men who died in the swim part of an Ironman competition this morning. Our sympathies to the families of these men and their friends and also to the volunteers manning the event.
Doubtless there will be serious questions to be asked of the organisers and if they arranged sufficient rescue boat coverage for a field that would spread out during the swim.
What I found very odd though, was that the event carried on with participants cycling and running. It'd be normal enough in bike racing or motor rallies etc for the event to be cancelled when there are fatalities.
Personally I don't think I could possibly just carry on as if nothing happened. Perhaps the competitors weren't aware of what had happened behind them but they could easily have been told.
Serious questions for the organisers....
