I love this heat and humidity!!

Lots of water. Don't forget to eat a snack because bonking in extreme heat does you no favours. Bring extra water to pour over your head to cool off. Ride thru every lawn sprinkler you can find. Favour tree lined streets and paths as much as you can. Eat Popsicles! So awesome
on a sweltering day. Especially the lime flavoured ones.

Oh yes, and slap on sunscreen.
