Rainy weather doesn’t mean you have to take your runs inside. And most races are notcancelled because of rain. So try these tips to make sure you’re prepared for running in the rain:
1. Wear a hat with a brim.
A hat with a brim can be your best friend during a rainy run. It will keep the rain off your face, so you can see, even in a downpour.
2. Dress in layers if it’s cold.
If it’s very cold and rainy, you may need to wear a couple of layers. The most important layer is the one closest to your body. Make sure it’s a technical fabric such as polypropylene or CoolMax, which wick water and sweat away from your skin. Your outer layer should be a wind- and water-resistant jacket or vest. Don’t wear a waterproof rain slicker because it will trap moisture and heat.

3. Don’t overdress.
4. Use a garbage bag.
5. Be visible.
Select outer layers that are very bright or light-colored and have reflective strips, since running in the rain often means poor visibility.
6. Wear old running shoes at the race start.
7. Prevent chafing.
If you’re running long, spread Body Glideor 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).
8. Protect your electronics.
Store electronics, such as your cell phone and iPod, in a ziplock bag or a water-proof carrier.
9. Just run!
10. Dry out your shoes.
When you get back from a wet run, take off your running shoes and stuff them with crumpled balls of newspaper. This helps the shoes keep their shape, and the paper draws moisture away from the shoes.
