Hi all! I've recently taken up running 7 days ago. Been on 4 runs last week between 3-5km. Im a 32 year old male. I currently weigh 73kg. I was quite active when i was younger but nothing since ive been 18/19. I was a smoker for 14 years which I quit last year and having been vaping nicotine for the past year which ive also quit since last week! The question i have is my vo2 high considering my circumstances? Are garmin devices accurate? Im confused by what ive read online regarding it. Thanks and happy running!
