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.

I've used this app for many years to train for my annual military PT test, it's just what I need to ramp up for the running portion. However this year, the app has been very glitchy. It doesn't properly alert you when to run/walk. Sometimes, the vibration cues don't work (I've verified it's turned on in the app, and it works in other programs) and sometimes the app tells you to run, but it's supposed to be on the walk cycle. And a few times, the app has crashed mid-workout. Going downhill, fast.

We understand how annoying that must be. We're working on a solution. We hope you'll re-consider the rating once we fix the issue.

The app can't handle overlapping your own route. If you run 2 miles in one direction then head back and end where you started, it thinks you haven't gone anywhere. The voice is far too soft with no controls, and there is no feedback as you're going. I used a 100% free C25K app a decade ago that was light years better than this. I thought it was this one based on the name, but I was sadly mistaken.

I was really hesitant to try this but I wanted to start running. I'm not athletic. I've never played sports. I'm overweight and almost 40 so I needed something to ease me in. This is easy to to follow and with the small increase every week, I feel like a champion when I finish it. Its hard and challenging but absolutely doable. Totally recommend just keep reminding yourself that you can do hard things!
