Where's Waldo?

I've taken a bit of holiday to see my wife, who's out of country. For those that know her, you know where she is and hence, where I am for the last few days and next few before I head back to Encinitas, then to Tempe to report on Ironman Arizona.

For those that don't, here's a guess test: what pool is this, and what group of athletes? It was taken just two days ago when I got to my destination. I'd love to give some hints, but that might give it away, and I think I'd love to see the guesses before I start revealing some more.

I'll elaborate a bit later, but for now, I'd love to see the guesses...
