Plenty of gyms offer workouts with virtual scenery. You can (stationary) bike through the forest and (treadmill) jog around the Grand Canyon. But running coach Marnie Kunz thinks that New York City has plenty to keep you entertained while you exercise without resorting to virtual reality. She created Runstreet, where she offers group runs on city streets, stopping to admire street art along the way. While you sip water and catch your breath, she talks about the artists and the meanings of the murals and graffiti you might otherwise fly by. The flame-haired sprinter chatted with us about her art on the run.
