This seven-week plan, developed by the experts at Runner's World, will help you transition from run/walk to running without walk breaks. This plan begins with a 25-minute run/walk and builds up gradually, so that by the end you'll be able to run for 30 minutes - without stopping! The plan includes four workouts per week with an optional fifth day. If you don't have time for the longest workout of each week, it's okay to split it in half. If you'd like to take a more gradual approach, you can repeat any week, or every week.
