First 5K

I've never been much of a runner, but just ran my first 5K due to this app. It broke down what felt impossible (running for 30 minutes) into a series of achievable goals. The first couple of weeks I repeated a few days, but soon found that I could keep up, even when a day's goal seemed so much harder than the day before (literally, running 3 minutes straight was scary the first time around). The pacing is perfect. Had no issues with notifications, as long as you remember to turn your phone off vibrate mode, which the app reminds you of when you start a workout!

My only objection is that although the app runs on time running/walking, the later workouts include a distance measurement (i.e. Run 20 minutes or 2 miles), which as a new runner was not an achievable pace (10 minute miles), so I used mileage tracking with a different app to compensate. It would be great if we could input an average running pace and have the app adjust its timing based on that. Anyway, still 5 stars because that wasn't too hard to deal with and by the time I got to that point, I was already comfortable enough on my own.

Seriously, I can't recommend this app or program enough. It's made a huge difference in my personal fitness and I can't wait to get up to a 10K over the next few months.

Flawed but gets results

Early forties, once skinny, step on scales - one ninety what the heck has happened? Desperation sets in - what to do? Run. Umm first run ends bad. I wonder, is there an app for that? Oh here one is with raving reviews. Week one, session one - that wasn't so bad but not any couch potato is going to get through that. After day 2 the new muscles are less sore. Hmm, 7 days later and I've completed week 2 - odd. Oh I'm supposed to do only 3 times a week. 3 more days and cripes! I can hardly walk my knees are so sore. Trip to running store - umm, I shouldn't run on sidewalk? And my shoes are worn out? Double cripes, if I can't run on sidewalk I can't do this. $120 and these shoes might work. Let's do it. Completed week 4 day one today. Crazy app lets me play pandora music in background. Love. If I lock phone, it doesn't announce when to run and walk. Hate. I lower screen brightness and leave on in pocket. Irritating, but it works. I feel my knees each run but not painful like before. I am getting through this and staying motivated. Love the running program and if app were reliable, this would be 5 stars. It doesn't notify way too often, so sometimes I don't think I've run enough. But easy to repeat. If you are chunky like me, buy new shoes before you start this for best results.

Exactly what I needed

This was the perfect app to get me into a consistent exercise routine. I was able to complete the entire 5K in about 8.5 weeks. Every other time in the last few years I have tried to get into a consistent routine ESPECIALLY with running I would only last 2 weeks and struggled to pace myself or be motivated to keep it up. This app helped me so much because it starts with small manageable times/distances that I could actually achieve and feel good about. It not only paces you with gradually increasing distances but literally paces you as you are running with voice alerts to start running or start walking--so no more fidgeting with a watch or phone timer that get you out of the zone while running. There were a few increases that seemed a little bit of a big jump but I went for them anyways and was pleasantly surprised that I was able to do it! If you are truly a beginner and struggle with any of the increases you can easily repeat days. I pair it with the mapmyrun app (because this app doesn't record/map exact distance) and it works seamlessly! All I can say is JUST DOWNLOAD IT (it's free) AND TRY IT (it might just work and you might just LIKE it)!!!
