The cooling stations are arches that spray water as you walk thru them.
Kinda like the mist nozzles you see attached to the edge of a canopy.

Any time you particpate in any kind of event you have to be prepared.

Remember this when you go to a outdoor music festival and find there is no TP in the porta potties.

The event organizers will tell you that there are out houses in the area, but will the TP hold up?
