I've been working on this for at least 8 weeks, but as far as the app goes I'm still fighting with week 4. That week has you run 3 minutes, 5 minutes, 3 minutes, 5 minutes. I run, probably, about a minute and a half, with comparable breaks. Some of where I run is uphill, so my flat or downhill runs are a little bit longer.
But I am making headway. A few days ago I corrected my form, and I think I'm going to make better progress.
