Does rainy weather mean we should take a different approach to running marathons? The thinking of most runners is that the cool conditions coming with the rainfall are more suitable than the heat anyway. In some cases athletes have reported beating their best previous times because of running in a downpour. It is achievable with a little extra planning beforehand. Firstly you must wear a hat with a brim to aid visibility. Next thing to do is to ensure prevention of chafing from all the rain getting in your clothes and shoes by rubbing up with vaseline before. Dress up in extra layers if cold, making sure the layer closest to the body is made from technical fabric like coolmax. Finally if possible get someone keeping a pair of dry shoes and socks halfway through your race , and you’re golden for the final half.
The reality is that ideal running conditions are cool days between 45 and 60 degrees. The rain can deifnitely help if the temperature is above 70 degrees because it keeps the body from overheating. This is important because the hotter the core temperature the more fluid and elctrolytes an athlete loses. Although these fluids can be replenished with water the hot waether does make the body work harder. This is exactly why avid runners look forward to a good rain.
