There are two questions I have. First I've only recently incorporated running into my program, I do it 3 times a week I'm at 35 to 40 minutes a run. I go by minutes, how should I incorporate more time? Should I go 2 more minutes next week and then keep it that way for two week and then add another 2 minutes and so forth? Also what Cathe workouts have you found very beneficial in improving your running? Thanks for your help
