How Does Temperature Affect Running Performance?

Temperature significantly influences running performance:

Cool Temperatures (45-55°F / 7-13°C): Considered optimal for running, as the body can efficiently regulate heat without excessive sweating. (runwindow.com)
Warm Temperatures (65-70°F / 18-21°C): Still comfortable, but hydration becomes more crucial to maintain performance.
Hot Temperatures (Above 70°F / 21°C): Increased risk of heat-related issues; it's advisable to adjust your running schedule to cooler parts of the day. (faant.com)

What Are the Best Humidity Levels for Running?
