☀️ Start early or run later in the day to avoid peak heat
☀️ Hydrate before, during, and after your run (don’t wait until you’re thirsty)
☀️ Wear light, breathable gear + don’t forget your hat and sunglasses
☀️ Choose shaded routes when you can - your body will thank you
☀️ Add electrolytes on longer runs to replace what you’re sweating out
☀️ Slow your pace and run by effort, not ego
☀️ Sunscreen is non-negotiable, even on cloudy days
