My fiancee wants to sell her Space Black Stainless Steel Apple Watch 3 and move to a Garmin full-time for training. No one in our training group uses an Apple Watch, nor do I see many of them at the start line of major races. But... since we're having a hard time selling it, even at a huge discount, I figure I could try to use it. I'm not as competitive as I was in college, but I run probably 60-70 miles per week, with probably a tempo and a track session included. Hoping to break 2:30 in the marathon. Does anyone run seriously with AW3? Do you use Strava? Workouts? How does it handle track work?
