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.

It has gotten me to my goal. I have used this app on and off for around 4 years. I have finally reached the end of running 5k. I think mentally it's super helpful for me to have an app that decides my workout for me. It takes the guess work away, and it's like an artificial personal trainer. You can listen to your music while running and the app interruptions are minimal. It's a well done, and beautiful looking app - that makes me want to click on it. Can't wait to try the 10k one!

This app LOOKS better than the other popular C25K app, and it claims to support syncing with MyFitnessPal too, which is why I tried it. Kudos to the UI/UX and integration teams. But you forgot to get the basics right! The seconds count down MUCH faster than real seconds (at least on my phone). So every round (1 of 8, 2 of 8, etc.) ends too quickly. While that might be celebrated by those who are glad when it's over so soon, it in no way prepares someone to run a 5K (the whole point of the app).

Absolute mess. The regimine is good, but the app on my galaxy watch 4 pauses randomly and without notice. I just ran 1.5 miles while the app was paused and I didn't know it. It also doesn't track distance accurately in the slightest. My last run, me and a buddy ran together. The app on my watch said we ran half a mile in 30 minutes. His GPS watch said we went 3.24 miles in 36 minutes. Just avoid this absolute mess if you're actually a beginner. Trusting it is going to leave you overextending
