VO2 Max Trainer: HIIT, Zone 2

Ghost Race is here. Run your Cooper test, Balke test or 1.5 mile run against a ghost: your best run, your 12-week goal, the athlete 10 places above you, the #1 of your age group, an Olympic record, or any VO2 max you pick. - Tap RACE next to START RUN - See the gap live, green when you lead, orange when you chase - Voice cues and a flash when you pass or get passed - Follow the race on the Lock Screen, Dynamic Island and Apple Watch, even without your iPhone - Your result saves as a normal test, with the race on top. Race again, or share "Me vs ghost" Built by one developer. If you like the update, a rating on the App Store helps a lot.
