I’ve done my fair share of rides in the 90s and even 100s. And I’ve learned — sometimes the hard way — that riding smart in the heat is the difference between a good training session and a dangerous situation.

1. Hydration Starts Before You Clip In

If you're waiting until you're thirsty to drink, you're already behind. I start hydrating the night before a long ride and take regular sips from the first mile on. I always carry two bottles: both with electrolytes to replace what I’m sweating out. My go-to: Elete Electrolyte Drops. I put these drops in my water bottles before leaving home and I carry a small squeeze bottle with the drops in it so I can put drops into any water I get on the road.  They do not change the flavor either.

Pro tip: Put one bottle in the freezer overnight. By the second hour, it’ll still be cold.

I also take money with me and stop at convenience stores to get more Gatorade or water if I need it.

2. Dress for the Heat

I wear lightweight, moisture-wicking jerseys, preferably in light colors. A mesh base layer might seem counterintuitive in hot weather, but it helps keep sweat from clinging and actually cools you as you ride. Of course I swear by Przewalski. I wear their bib shorts as well. Very well made and not as expensive as the rest.

 And don’t underestimate a good pair of UV-protective arm sleeves — they keep the sun off and stay cooler than bare skin. These are some of the 10 pair I have purchased and use everyday.  It sure beats the mess of sunscreen on my hairy arms and they actually do cool my arms, even in 100 degree heat.

3. Know the Signs of Overheating

Heat exhaustion can sneak up on you, especially on a climb or into a hot wind. If you start feeling dizzy, weak, or stop sweating, that’s your body flashing warning lights. Stop in the shade. Cool off. Pour water on your head or neck. Don’t try to “tough it out.”

4. Plan Your Route with Heat in Mind

Some roads offer shade. Some have gas stations or stores where you can refuel. When it’s hot, I plan routes that keep me close to options if things go sideways. On extreme days, I’ll shorten the ride or ride loops so I can bail out if needed. Take it from me, it is okay to call someone to come pick you up. Better to ride again another day than to never ride again. No shame in being smart.

5. Timing is Everything

If possible, I start earlier to beat the worst of the heat. But when that’s not an option — and let’s face it, some training rides need to simulate tour conditions — I embrace the heat, but I adjust my expectations. Speed isn’t the goal. Endurance and safety are.

It’s Not About Braving the Heat — It’s About Respecting It

Cycling is about pushing yourself — but pushing through heat without caution can land you in real danger. I don’t let high temps keep me from training, but I do train smarter. The heat will test your grit. That’s part of the beauty of it. But so is making it home safe, tired, and proud of the ride.

If you’re training for something big this summer, ride on. But ride smart. The sun’s got plenty of strength — make sure you do too.
