I am looking over the “18 weeks to IM” training program put together by Mark Allen. I was amazed at how low the intensity is for most (almost all) of the program. He mentions that the individual ceases to experience aerobic improvement from training when the heart rate goes above their maximum aerobic heart rate (MAHR). From the formula, mine is about 150 beats per minute. I would have to say that most of my training has been between 150 and 165 bpm on the run (I haven’t been monitoring for the bike and swim). Am I defeating the purpose by training “too hard” even though it does not feel too hard? Am I training to hard? Have I still been benefiting aerobically?
150 max heart rate on a run would feel incredibly pedestrian and will take alot of mental restrain. I have the mentality that if you train fast you race fast as long as you get proper recovery between workouts. If 135-150 bpm means that my run pace does not go below 8 minutes/mile (whereas I am about a 36 minute 10k’er right now), am I not training my muscles to run slow???
