Choose the right sunscreen.Use a waterproof sunscreen that has an SPF of at least 15 and offers broad spectrum protection, which means it protects against both UVA and UVB rays. Stick formulations are good for runners' faces because the sunscreen won't run into your eyes.

Run early or late.Try to avoid running between 10 a.m. and 4 p.m., when the sun's intensity is at its greatest. If you must train during those hours, try to stick to shady roads or trails.
Wear a visor or hat with a brim.A visor or hat will give your face extra protection. (Although you'll still need sunscreen on your face.) It will also help absorb sweat, so the sunscreen doesn't run into your eyes.

Put on your sunscreen ahead of time.Slather on your sunscreen at least 20 minutes before you head out for your run. Your skin needs time to absorb the lotion.
Don't skip sunscreen for short runs.You can get a sunburn in as little as 15 minutes, so don't think doing a short run means you don't need sunscreen.
Sunscreen starts to lose effectiveness at about the two-hour mark, or even sooner if you're sweating heavily, so you'll need to reapply if you're doing a long run or race. Carry a small tube of sunscreen or a one-use, sunscreen wipe in your pocket, so that you can reapply it to your face, neck and arms as you run.
