Should I go by HR or pace during “AnT Intervals”? (Beginner Marathon Plan)

    Hi,

    For the “AnT Intervals” workouts of the 24 Wk Beginner Marathon Training Plan, the training plan calls for… “4x 5min running at AnT HR with 3 min walking recovery.”

    My AnT pace is 8:30 min/mile @177 bpm (as determined by field tests).

    If I do my intervals by heart rate, I have to run 7:15 min/mile to get my heart rate up to AnT HR within the 5 minutes. I think this is due to HR lag. If I go by pace and run 8:30 min/mile, my heart rate never gets to 177bpm and hovers around ~163 bpm.

    Should I go by heart rate or by pace during the 5 minutes?

    Thanks!!

    HR lag is always an issue in interval training. In your case since the lag is long and the difference in pace 7:15 to 8:30 is large I would recommend doing these at 8:30 for the first session and see how you recover. If you feel good the next day or by two days after then do the next session at 8:15 and continue that way. This will be better than to do the first one a 7:15 and find that you are wrecked for 4 days after or unable to complete the workout at that pace.

    Sneak up in the intensity gradually.
