Heat changes the rules of racing and brings real risks: dehydration, heat exhaustion, even heatstroke. When temperatures rise, the effort that feels comfortable on a cool day can quickly turn punishing.
But hot races aren’t impossible. With the right adjustments to gear, pacing, and preparation, you can protect your health and give yourself the best chance to reach the finish line in good form.
These seven strategies will help you navigate the heat and handle tough race conditions safely.
1. Start hydrating early
Don’t wait until race morning. Begin hydrating steadily in the 48 hours leading up to the event.
Electrolyte-rich fluids support your body’s heat defense system more effectively than plain water alone.
Drink to thirst—but make “pre‑hydration” a structured part of your buildup.
2. Adjust your pacing expectations
Heat isn’t just physical—it distorts effort. Even well-trained runners may slow significantly.
Accept starting conservatively, and focus on managing effort, not chasing pace.

3. Wear light gear and protect from the sun
Choose technical fabrics—light colors, breathable wicks—not cotton.
Apply a reliable sunscreen before the start, and consider a breathable visor or UV-blocking sunglasses.
These choices may slow heat gain and reduce skin damage.
4. Hydrate and fuel at every aid station
Every water stop is a chance to cool and refuel. Alternate between water and electrolyte drinks to replace sodium lost through sweat.
Pouring water over your head, neck, or wrists offers instant cooling relief.
5. Cool your core during the race
Take advantage of ice packs, cold sponges, or misting tents when available.
Focus cooling efforts on your neck, underarms, or wrists, where sensors help bring down overall body temperature faster.
6. Watch for warning signs—then act
Heat illness doesn’t always announce itself. Nausea, dizziness, tingling, or confusion? Slow immediately. Heat exhaustion can escalate rapidly. Prioritize health over a finisher medal.
7. Adjust your mindset
Reframe success: finishing upright, healthy, and non‑injured should be the priority. In high temperatures, survival and safety outweigh personal bests.
