In this Q&A I answer questions from Jim. He has read Simple Marathon Training and his questions are well informed. Thanks Jim! His questions are as follows. 1. Do you always prescribe minutes to even advanced runners? If so, why? 2. Can you run your easy days too easy? 3. During your fundamental phase, do you see value in hill sprints as well? 4. During your foundational phase, do you see value in starting to progress a moderate speed long run in distance to prepare for marathon-specific training?
