Del, I don’t have a Garmin but my Apple Watch provides a VO2 max reading based on hr and blood oxygen levels and an algorithm that puts mine at 46.5 , up from 32 ,3 weeks ago. I have no idea how accurate it is but I know that compared to my pi$$ poor cheddar gorge effort, where I struggled to breath with the effort of riding hard, I had no such issues today. Well, apart from the usual ones.
Your name popped up in some of my segments today. As did Tommy’s. You two might want to come out this way again and get back some credibility 👍😁
