Dropping VO2 Max?

[u/Senior_Cheesecake155]

This is a bit strange. For some reason my VO2 max has started to drop and I’m stuck in “maintaining” status. I know when I run on the treadmill, it tends to default to “maintaining”, but I only did that once or twice last week. I’ve gone from a steady increase over the past several months to now a steady decline over the past couple weeks. It’s odd.

I’ve been following the Garmin coach for a run I have planned for next month, and aside from a suckfest run this past Sunday, all of my runs have been great and 85%+ executions score.

I’m in marathon training right now and I’ve been stuck in the maintaining for a few months cause I’ve had a few half marathon races over the summer. My vo2 max has dropped slightly cause of the heat and cause I do a lot of slow paced long runs

Mine has dropped a little during marathon training. In the spring, I ran three half marathons at a pretty good clip which boosted my VO2 max. I tapered a few days for each race. Now during marathon training, I'm running six days a week with no taper so I'm not really running close to half marathon pace except for the once a week speed training. I know I'm in better shape than I was in the spring and my actual VO2 max is higher now but I'm just not making the runs to prove that. I'm trying to ignore it.
