I have used the C25K app and now am on the 10K free app. Out of curiosity, I downloaded the 13.1 app. But this seems a totally different kind of app. Very little running. Run 4min/walk 2min? What is that all about? I can do that in my sleep. I expected the app to be more brutal than the 10K app. Am I missing something?
