answer:i found this on Google. Prevent Chafing If you’re running long, spread Body Glide or Vaseline on parts of your body where you would normally chafe or get blisters—such as your feet, inner thighs, underarms, sports bra lines (women), and nipples (men). Wear a Hat A hat with a brim can be your best friend during a rainy run. It will keep the rain off your face. Don’t Overdress This is one the biggest mistakes runners make when heading out for a rainy run. Wearing more layers will not keep you dry. Unless you’re running with an umbrella over your head, you will definitely get wet. If you have tons of layers on, you will just be wearing more wet, heavy clothes. Dress for the temperature, as if it were a dry day.
