I am an 18 year old cross/track athlete I run in D3 Michigan. I had a Garmin forerunner 235 for about 2 yrs but the HR monitor was cracked and did not go above 160 ever. So when my Vo2 max cam out to 70 I wasn't surprised considering my HR monitor was broken but I recently got a Venue SQ and instead of my Vo2 Max decreasing like I expected it went up to 72 this seems inaccurate to me. I run 4:36 1600m for reference.
