when would your 5k times be better?

I'm new to running. When would your 5k times be better? In cold dry air, say in the 20's or warm summertime in the 80's everything else being equal.

    environmental conditions have a big impact on running performance and just as there are "morning" people and "evening" people, there are cold weather runner and hot weather runners.

     

    However, hot weather tends to raise the core temp and so your heart is already working harder to pump blood to cool the body so it is ofen expected that running in cooler temps will result in faster times.

     

    If you listen to post-race news, you will often hear of how the weather had an impact on the times - Boston is a classic.  Hot day in Hopkinton means a longer time to reach Copley Square.

    depends on how hot ... cold air is usually dry, warmer air contains more water, thus more oxygen and so lungs get more instant oxygen; however, once your body has to work too hard to cool itself, heat becomes problematic

     

    For me, I run way better at 60 degrees than 20 or 80

    Here in South Florida my times are optimized when:

       1. Temps are in the 50's.

       2. Humidity below 50 (a rarity in So Fla). High humidity

          is worst than high temps, as the your sweat does not

          evaporate and your body does not lower it's temp.

       3. Slight downhill

       4. Wind at your back.

       5. Following at good looking babe

       6. flat course
