Summer running can be incredibly rewarding—but it also comes with unique challenges. Higher temperatures and humidity place additional stress on your body, making even an easy run feel harder than usual.
The good news? With a few smart adjustments, you can continue building endurance all summer long while staying safe and healthy.
1. Prioritize Hydration
Hydration starts long before you lace up your shoes.
Drink water consistently throughout the day, not just right before your run. For longer runs or especially hot, humid days, consider bringing a handheld water bottle or wearing a hydration vest. If you're running for more than an hour or sweating heavily, replacing electrolytes can also help prevent cramping and fatigue.
A simple way to gauge hydration? Your urine should be light yellow—not dark amber.
2. Choose the Coolest Time of Day
The easiest way to beat the heat is to avoid it.
Aim to run:
- Early in the morning, before temperatures climb.
- Later in the evening, after the sun begins to set.
Not only will you be more comfortable, but you'll also reduce your risk of heat-related illness and excessive sun exposure.
3. Dress for Success
Your clothing can make a huge difference.
Choose:
- Light-colored clothing that reflects sunlight.
- Moisture-wicking, breathable fabrics.
- A lightweight hat or visor.
- Sunglasses to protect your eyes.
- Sunscreen—even on cloudy days.
Skip heavy cotton, which traps sweat and heat.
4. Slow Down Without Feeling Guilty
One of the biggest mistakes runners make in the summer is trying to maintain the same pace they run in cooler weather.
Heat and humidity naturally increase your heart rate, meaning your body is working much harder even if your pace is slower.
Give yourself permission to ease up. Running by effort instead of pace helps you train smarter—and often leads to stronger performances once temperatures cool down.
5. Listen to Your Body
There's a difference between being uncomfortable and being unsafe.
Stop your run immediately if you experience:
- Dizziness
- Chills or goosebumps despite the heat
- Nausea
- Confusion
- Excessive fatigue
- Headache
These can be early signs of heat exhaustion. Find shade, cool down, hydrate, and seek medical attention if symptoms worsen.
The Secret to Becoming a Better Summer Runner? Embrace the Heat.
Whitney from The Mother Runners says:
"The best way to get used to running in the heat is to embrace it. Running in the heat can take a couple of weeks of daily exposure. Still, when you do, not only does running feel easier—your body becomes more efficient at processing oxygen, setting you up for faster running when the temperature cools."
In other words: those slower, sweatier summer miles are building fitness you'll appreciate all fall long.
