If you’re a monthly subscriber, yes! You can switch between training plans however you’d like. Just go to your dashboard and choose the “change or restart plan” option. This will take you to your training plan menu. Of course, we do recommend that you finish a training plan once you’ve started it (unless you find it to be way to difficult or easy), since they’re designed to build your fitness over weeks. When you leave a training plan in the middle, you’ll miss key workouts; and when you start a new plan, you’ll start it from the beginning. This is to make sure that you train safely and responsibly, and that the skills you develop are built to last. We encourage you to stick out each plan, challenge yourself in a race or other personal challenge, and then to start a new plan with fresh legs.
