I'm about to start week 5 (where the first of the "run 'x' distance (or 'y' minutes)" runs appears) and have become incredibly discouraged. I have been training with a treadmill so that I can train evenly with consistent pace. The best I can manage on the 5 minute jogging sections (that I can sustain for the who section) is 4.1 mph. To make the week 5 times work, I would need to be running 6 miles an hour. My brisk walking pace is 3.0 mph, but at 4.1, I cannot hold any semblance of conversation, so i don't think I am taking it too easy. I see on the forum that many people graduate without the ability to run the whole 5K (3.1 miles) in 30 minutes (you must average 6.2 mph), but I with that either A. the app allowed you to input your pace, and would by mathematical formula adjust the schedule to ACTUALLY get you to 5K (what is claims it does). or B. allowed you to pick by time or by distance training modes (that might result in a longer training schedule) so that if your pace is slow, you can still actually finish. As it is, I am going to "graduate" while only being able to complete ~67% of the race, and then I'm on my own. It's frustrating to say the least. Thoughts on how to train up the last 15-20 minutes in endurance?
