As I write this post, the sun is shining, the birds are chirping, and the mercury is climbing. It’s humid, hot, and I’m running tonight. In a futile effort to stay cool, I’ve collected some of the best hot weather running wisdom.
1. Modify your runs. First, and most importantly, modify your runs and make adjustments to accommodate the heat. Don’t expect blazing fast times on boiling hot days. Save speed work for cooler days, and cut back on your pace when running in the heat. Consider modifying your training plan to run fewer miles at slower paces for the duration of a heat wave. Be patient and allow yourself to adapt slowly to the heat.
2. Mix it up. Take your runs inside. In the worst heat, consider running on a treadmill or indoor track. Runners World magazines’ online resources include some great suggestions for excellent treadmill workouts, perfect for the hottest of days. Taking speed work inside in hot months ensures that you’re training well, and safely. Consider including more cross training with swimming, surfing, kayaking, paddleboarding, and cycling. Pool running is a great option for those with handy pool access.
3. Think shade. When the weather’s hot, run your runs in the shade and at the coolest times you can manage. Run early in the morning when the weather is the coolest, or in the evening when breezes are more likely to come up. Run on shaded paths or in neighborhood with trees. Consider plotting a route that takes you past shops or big box stores so you can duck in for a little air conditioning – or bail on the run entirely. Run on the grass or on a trail if you can.
4. Chill out. If you’re planning to run in the heat, take precautions. Wear sunglasses and sunscreen. Wear loose fitting clothing made of wicking material, and as little of it as is reasonable. Wear a hat or visor to keep sun off your face. Some evidence suggests that cooling the extremities before and during hot runs can help, so consider wetting your head, carrying a wet cloth, or even putting ice in your clothes. It’s crazy, but it works. Some runners also swear by drinking an ice cold drink just before the run.
5. Carry water. Hydrate early and often with water and, if necessary, an electrolyte replacement product. Consider your individual hydration needs and plan accordingly. Not sure how much you need to drink? A quick consultation of google will tell you everything you need to know about how to hydrate and what to avoid.
6. Consider your non-running activities carefully. Alcohol, antihistamines, and antidepressants can all have a dehydrating effect. Using them regularly, or before a run, can put you at greater risk of heat-realted illness due to dehydration. Talk with your doctor about how to take your medication, and stay safe in the heat.
Finally, protect yourself. Know the signs of heat-related illnesses and take steps to prevent problems before they start. Here are some of the basic heat-realted illnesses, including their signs and symptoms. As always, consult with your medical professional with regard to heat safety.
When dehydration leads to an electrolyte imbalance, large muscles cramp. Restore balance with good hydration and stay well hydrating during runs.
When excessive water intake dilutes blood-sodium levels, headache, disorientation, muscle twitching can result. Emergency medical treatment is necessary. To prevent problems with hyponatremia, don’t drink more than about 32 ounces per hour and consider a sports drink over water. Talk with your medical professional about your hydration needs.
Dehydration can lead to an electrolyte imbalance that results in a core body temperature of 102° to 104°F. This causes headache, fatigue, profuse sweating, nausea, and clammy skin. Restore balance with good hydration and stay well hydrated during runs. Slowly cool down by applying cool water the the head and neck, seek the shade and get out of the heat.
Heat stoke occurs when exertion and dehydration prevent your body from being able to regulate core temperature. Core body temperature can exceed 104° or more. Heat stroke is usually accompanied by headache, nausea, vomiting, rapid pulse and disorientation. Seek emergency medical treatment immediately if heat stroke is suspected. Emergency personnel will cool and rehydrate the individual safely. While waiting for help, get out of the heat and cease activity.
Stay cool, my running friends.
