Cooling Off

Staying at a Premier Inn in Nottingham tonight as I have an open water swim to do tomorrow at the national water centre here. Have been and registered already. Picked up my hat and chip timer.
I'm doing 2.5k Which is a distance I've not raced at before.
Quite a few swimmers going off in the same wave as me. 300+. Not all doing 2.5k, some are doing 5k.
Nerves kicking in a bit, but looking forward to it too.
