By day, Kristina Rodulfo is a senior beauty editor\u2014which means she's busy tracking lipstick trends, directing photo shoots, and running off to beauty industry events. But it's after hours when she really kicks into high gear: training for her first New York City Marathon. "I have two passions in life\u2014writing and running," she says. "I first fell in love with running when I was on the high school track team, but it fell off. So, I set a goal for myself: I am going to run the New York City Marathon." On November 4, 2018, Kristina will join about 50,000 other men and women from all over the world to trek 26.2 miles through all five boroughs of New York City. As an NYC-native, this goal has particular meaning for her. Kristina's training includes doing some kind of cardio every day. Her Fitbit Versa \u2122 silently reminds her with a subtle vibration and flicker of light when it's time to switch gears into training mode. "I run four to five miles every day, and as long as I have good music in my ears, I can keep a pace and stay motivated," she says. She loads her Fitbit Versa up with playlists that keep her pumped, and starts a run in the Exercise app to track her progress\u2014not just the distance, but her heart rate and calories too. This way, at the end of her run, she can sync her watch to the app and compare her progress over the week.
