Sunscreen and water. On the grounds of the TT, quite a bit of sunscreen is put on the bodies and a lot of water flows through the bodies.
Not so crazy with the summer conditions. People come and go at the taps for some cooling water. That goes beyond just filling the bottle of water. “And when the water starts to evaporate, it pulls the heat out of your head”, is the theory of someone who holds his cap under the tap and then puts it on his head. “Lovely.”
