When running a marathon, the weather can really affect how you perform. Here are some tips on how to adjust your running pace based on the weather:

1. Temperature Changes:

   • If the temperature goes up by 5°F above 60°F, you should think about slowing down by about 5 to 10 seconds for each mile you run.
   • The best temperature for running a marathon is between 50°F and 60°F.

2. Humidity Levels:

   • When the humidity is high (over 70%), it can make it harder to run well, and your performance might drop by up to 15%.
   • Make sure to drink 20-30% more fluids when it’s humid.

3. Wind Effects:

   • Running against the wind can slow you down by about 2-3% for each mile.
   • Try to run in a way that helps you reduce the impact of the wind, like running behind someone else for protection.

4. Running at High Altitude:

   • For every 1,000 feet higher you go, you might need to slow your pace by 1-2%.
   • Give yourself enough time to adjust to the high altitude before the race; aiming for at least two weeks is best.

By paying attention to these weather factors, you can adjust your pace and have a better marathon experience!
