When is the Best Time for a Run?

What time of the day do you run? I prefer running in the morning simply because I feel energetic after doing so.  There’s no sufficient research about the best time to run but based from this research, night runners would be really grateful!

After you awaken, your body is in a “heat gain” mode to increase its core temperature, so the body shunts blood flow to the extremities. In the late afternoon and early evening, your body is in a “heat loss” mode and blood flow to the extremities is increased.

It’s unclear whether this is the primary cause of increased athletic performance in the late afternoon and evening, but it makes sense from a physiological point of view: in the evening, your body is already primed for shedding excess heat, which is a necessary part of exercise. We know from studies on exercise in hot temperatures that your brain appears to limit your body’s ability to perform when it can’t get rid of excess heat fast enough.

However, other factors probably play a role too, since various hormone levels are known to fluctuate throughout the day as well (a point made by Waterhouse et al.). Some additional questions arise when we begin to consider the ideal time to schedule an event in the heat: should it be in the evening, when the body’s thermal radiator is already primed? Or should it be in the morning, when there is more “headroom” between the body’s set temperature and the maximum safe temperature tolerable during exercise? This is an issue that’s yet to be resolved with research.
