Hi there,
I started the 5K Greg McMillan plan and have found it not very adaptive to my needs. Even though I set the ratings to very difficult it keeps accelerating me through the program. If I can't run for 10 minutes straight why am I being asked to run for 15 and then twenty in the same week?
I was on Reddit and it appears many people have the same issue. One person said no matter what parameters they put into the program they get the same workouts.
There should be an option to back up the program so that people can work their way up to improve. Currently I feel it would make a lot of people want to give up.
