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...
Yesterday I reached optimal anaerobic effect for the first time ever. The difference is that I've started using the daily suggestions. Threshold, sprint, anaerobic, VO2max and so on.
Unless you're really trying to train for something specific, I would just ignore it. I mainly cycle and I have enjoyed riding much more since I got rid of my bike computer and power meter. I still track rides with strava of course, but not having all the numbers during my ride let's me just enjoy it. I also quit wearing my garmin watch on runs for similar reasons.
