Until a few months ago, my winter mountain biking routine had a problem: It was missing the camaraderie of group rides. During the spring, summer, and fall, I can ride side by side with friends through the hills. But when the weather turns cold and snowy, it’s not ideal to bike outdoors. I stay in shape by pedaling inside on my old CompuTrainer, but there’s no nature to look at, and without my friends, I feel less motivated. This winter I discovered a solution: the online biking platform, Zwift.
