Whatever variety you go for, make sure to apply sunscreen at least 15 minutes before heading outside, which gives your skin the chance to absorb the product so you don’t sweat it off right away. Then, you should reapply every two hours you are outdoors. Nossa suggests setting up sunscreen along with the rest of your gear in your transition area. “Before you grab your bike or as you run out of transition, you can quickly wipe down your body in areas that need the most protection, like your cheeks and nose,” says Nossa. And don’t forget your lips. “Statistically, men have a much higher rate of skin cancer on the lips because most women wear lipstick, which offers some form of protection,” says Jackson. As with the sunscreen, you’ll want to reapply your lip balm (try Jack Black Intense Therapy SPF 25, $7.50, Getjackblack.com, and Scape SPF 50+ Lip Balm, $3.50, Scapelabs.com) every couple of hours or more if you feel your lips are drying up. “Worse case: Take whatever you’re using on your skin and put it on your lips. Just be careful you don’t ingest it,” says Jackson.
