VO2max Calculator This calculator will generate training paces and race predictions. The calculator works by estimating your VO2max using a generic mathematical model based on a previous run of yours. It works reasonable within 1500 meter to marathon runs. You may have several race results that indicate different VO2max values. If the races are all reasonably recent and reflect your current fitness level then use the best. If you have been injured or had a break from training since your last race - you should not use an old race result. Run a new test instead. The calculator uses mathematical formulas. The VO2max estimate in this app is a measure of how fast you are. It does not care how much you weigh or how much oxygen you take in. It should be used as a framework for training. A real VO2Max is a physiological measurement, essentially based on your maximal oxygen uptake and your body weight. This is only a tool. Always consult a professional before implementing these estimates in your training.

Your VO2 max, explained. Your Fitness Age, your trend, and a coach to talk it through. VO2 max Hero reads the cardio fitness estimate your Apple Watch saves to Apple Health and turns it into something you can act on: where you stand for your age, which way you're heading, and what moves it. FREE • Your latest VO2 max, the 30-day change and a 90-day chart • Why it moved: the outdoor walk, run or hike behind each new reading • Fitness Age: the age whose typical cardio fitness matches yours • Your best reading and your 30-day progress • An Apple Watch app with complications • Home Screen and Lock Screen widgets • A note when a new reading lands PRO • Coach: ask about your numbers and get a short, plain answer, then follow up in the same thread • Monday brief: last week in one card • Your rank among people your age and sex, and how far your next Fitness Age is • Your full history, year over year, and your pace • Four more hero styles and four more colors Pro is a monthly or yearly subscription, with a 7-day free trial for new subscribers. Coach has a fair-use daily limit. HOW READINGS WORK Apple Watch (Series 3 or later) estimates VO2 max during outdoor walks, runs and hikes recorded in the Workout app. Indoor workouts don't add readings. No Watch? Any VO2 max already in Apple Health still works. PRIVATE BY DESIGN No ads. No tracking. No account. Your Health data stays on your iPhone unless you ask Coach a question. Coach sends only the numbers it needs to a third-party AI service, and only after you allow it. You can turn that off in Settings at any time. Fitness Age compares your VO2 max with published treadmill norms for your sex (the FRIEND registry). VO2 max Hero gives general fitness guidance. It is not a medical device and doesn't diagnose or treat anything.
