This plan offers a library of 31 days of swim workouts that progress from 500 yards to 1500 yards. Sessions include a focus on form, endurance and pacing. The workouts encourage new swimmers to focus on specific aspects of form to help build efficiency in the water. These workouts are useful for beginner triathletes, who can easily mix the sessions in with other bike and run workouts. These sessions will also prove useful for cross training for cyclists or runners who are looking to vary their weekly training routines.
