I consistently have a lack of anaerobic load in my Garmin training load. I did a track run today trying to work on intense intervals. I was hoping to get to the end and have more anaerobic effect than aerobic. Is there something I should be doing differently in my runs? I was under the impression that the rest phase between run intervals should allow you to really catch your breath, so I often walk for a few seconds before getting back into a jog in my rest interval.
Should I be more focused on keeping my pace up during the rest interval? Should I be running fewer/more intervals? Should I ignore these stats and just enjoy the run?
Are your heart rate zones set correctly? One reason I ask is that they sometimes reset themselves spontaneously on my watch. But either way, if they're set at a level where you can't spend time in the anaerobic zone...
