"C25K is easy to use, as expected for a beginner application." - New York Times "Daily programs that alternate between short bursts of walking and running until you are ready to reach the distance." The proven C25K (Couch to 5K) program was designed for inexperienced runners who are just beginning an exercise routine. The structure of the plan prevents the new runners from giving up and at the same time challenges them to keep moving forward. C25K works because it starts with a mixture of running and walking, gradually increasing the strength and endurance to fully run 5K.
