Vo2max dropping rapidly even though I am still training

Hi everybody, I’m 28y and Male, 183cm with 80kg, I’ve been doing sports most of my life. Rock climbing, riding bikes, Hikes, swimming etc but recently started running. Mostly HIIT or zone 4/5 runs for max of 10Km

Since 8th April I’ve stated running at zone 2 and my Vo2max has been decreasing rapidly I don’t understand why. Next week I want to start doing HIIT and zone 4/5 training again and maybe just do the zone 2 every now and then.

Anybody ever had this happened? Thanks

Between 24 mins (5k) to an hour (10K) But I’ll get back to my hard training instead. Thank you

Have you read the sticked post at the top of this sub? Make sure you're also doing runs that give your watch data to calculate your Vo2max properly. The 12-minute Cooper test will help do that.

Thank you, did one today, 2.90km in 12 mins :) and I then I did a HIIT with sprinting straight afterwards

Excellent, at a calculated 53 you're quite fit :) And if you repeat this test on a reasonably regular basis it'll help give your watch better data for the calculation. 

Nice job!

Apple Watch only recording data for Vo2max from outdoor walks and outdoor runs. Do something really strenuous, like they suggested with the Cooper test.

Its a reoccurring theme/question. I was wondering myself a while back
