No Cycling VO2 (Vectors are paired to fenix and I have a HR monitor)

Guys,

I cannot get a cycling VO2.

Setup:
I have the vector 1.
Software is up to date
Vectors are connected to my Fenix 5
Power data is being shown / updated / captured

I am using a Scosche HR monitor
It is paired to the fenix 5 as well

I am training indoors on a trainer.

Fenix 5 is up to date

I have never been able to get a cycling VO2. I am able to get running VO2 (granted I haven't run outside in ages)

Thoughts?
  • VO2 max can be a bit tricky to get if you don’t have the full facts.
    First off, you will need Heart Rate and Power data to get VO2 max while cycling. Plus, you will have to sustain a moderately hard ride for a total of 20 minutes.
    Other tips would be to make sure your Heart Rate is between 70% to 100% of your Max Heart Rate. Maintain a constant power output (no drifting). Avoid rolling terrain. Avoid group rides where there is a lot of drifting off the other riders.
