C25K® is the easiest program to get beginners from couch potatoes to 5K distance runners in 8 weeks.

The proven C25K program was designed for inexperienced runners who are just beginning. The plan's structure prevents new runners from giving up and challenges them to continue moving forward. C25K works because it starts with a mix of running and walking, gradually building up strength and stamina.
