I singed up for a 3.2 mile open water swim that I'm super excited about they will actually pull you out of the water if you don't make the 2 hour cutoff! Which means the competition is going to be fierce!
I also signed up for a half ironman as a practice race. Which I find funny because I spent months last year for one half Ironman!
That OWS sounds awesome! It is a stiffer cutoff than the 3.1 mi that I did last year. I think they gave people 2.5 hours? I can't remember if everyone finished. They gave 4.5 hours for the 10k, and there were definitely people that didn't finish that. You will surely not have to worry about that though.
