“As a runner, the sun is my only job hazard,” said 2004 Olympic marathon bronze medalist Deena Kastor. “I try to stay inside during the middle of the day when the sun is directly above, but even morning sun can do damage, so always be cautious.” Kastor, the American female record-holder in the marathon, has endured three bouts of malignant melanoma and now never runs without a hat and sunscreen—she’ll also don sun protective clothing if she’s running for more than two hours.

*UPF stands for ultraviolet protection factor and indicates how much of the sun’s ultraviolet radiation is absorbed by a person. According to the Skin Cancer Foundation,, clothing manufacturers that indicate their fabrics to have a rating of 50, for example, will allow only one-fiftieth of the sun’s UV rays to pass through the fabrics, translating to significant reduction in UV radiation exposure.
