Does the time of day effects how fast you can run?

Answer 1

First off I would like to say that I am not an expert, but I have been doing a lot of reading on this subject lately. I don't believe the time of day has a direct effect on how fast you can run, but there are some factors to consider that could possibly have a direct effect on your bodily functions and indirectly affect how fast you run. The main thing to consider is your metabolism (how fast your body turns food into energy). If your metabolism is at max speed, you will have more energy to run & have a higher endurance while running at a high speed. Your metabolic rate is generally higher earlier in the day (this is not true for every one, are you a morning person or a night person?). So if you were to be running in the morning, you would theoretically run faster. Another thing which could be an answer to your question, is the weight of your body. It is clear that having more weight will slow you down. So would a person that eats all day be slowed down at night? The factors that could make this theory differ from person to person are: how much someone eats, what they eat, when they eat, their metabolic rate, and when they go to the bathroom.
