Running in hot weather has always been a challenge for me. The discomfort of a red face, sweat dripping into my eyes, and the fatigue that sets in even after a short run used to frustrate me endlessly. But as the heat and humidity rise in Atlanta, it’s time to start preparing for those tough summer runs.
In early June, the temperatures often reach the high 80s and low 90s, and while we can’t change the fact that it’s going to be hot, there are steps we can take to prepare our bodies and minds for the heat.
Why is running in the heat so difficult?
- Dehydration – Dehydration can be much more dangerous than many people realize. As the temperature rises, we sweat more, leading to greater fluid loss. This increases the risk of heat-related illnesses such as heat stroke, which can even be fatal. Dehydration also negatively affects your ability to train and recover properly. It’s crucial to recognize the signs of dehydration so you can address it before it becomes a serious issue. Signs of dehydration include:
- Thirst
- Headaches
- Muscle cramps
- Dry eyes or mouth
- Fatigue
- Dizziness or lightheadedness
- Mental confusion
- Weakness
- Elevated body temperature
- Sweating becomes less effective – When you run, your body generates heat, and sweating is how it cools down. About 90% of the heat is lost through evaporation. However, when humidity is high, the moisture in the air makes it harder for sweat to evaporate, trapping heat in your body. This can cause an imbalance of salt in your cells, which can be life-threatening if not managed.
How to prepare for running in the heat?
- Replenish after each run – After every workout, make sure to restore your water, electrolytes, and glycogen stores to support your body’s recovery and keep your energy levels up.
- Acclimate gradually – If you’ve been running indoors during the cooler months, it will be much harder to handle outdoor runs in July. Try to transition to running outside regularly so your body can adapt to the heat over time. Consistency is key in getting used to warmer conditions.
- Adjust your expectations – Running in hot weather requires more effort, so don’t expect to hit the same pace or time you would in cooler temperatures. Be kind to yourself and adjust your expectations. By doing so, you’ll avoid unnecessary disappointment.
- Use technology – Apps like Runners Connect offer online calculators that help you adjust your pace based on temperature and humidity. These tools can be invaluable for managing your effort and preventing overtraining during the hot months.
Stay safe, stay hydrated, and good luck with your summer runs!
