Schools are letting out which means summertime is here. If you had any doubt, check the weather forecast for today. It's going to be HOT, which means there's a very strong likelihood of training outdoors.
It's hot. Start dealing with it now. If you know you'll be training outside from 6:30-8:30, plan for it now. That means, right now, put your phone down or walk away from the computer and down a glass of water. So much of taking care of ourselves in the heat is about hydrating hours before training.
On these warmer days, think ahead. Speaking from experience (Phoenix 50), dehydration is a monster.
