Guess who?

I did a fourteen length swim with Richard this morning. Wearing my neoprene hat made a big difference, I'm told David made it 10.5°C yesterday. It was clear and bright but the sun hadn't reached the water while I was swimming. I took the pictures below after I got out, hands in the water to grab an image. Who are these three swimmers?

Coming in at an angle who could this be? Click on the image to see it bigger.

Not so clear but the trademark bubbles might give away the identity of swimmer two.

This one is easy to anyone who's looked at my blog more than a few times, I love the reflection.
