Simple Pace vs VO2max Calculator

Distance, time, pace and speed, always in sync. Change any one and the others follow. A lock holds the value you care about while you work out the rest. On a relay team, or waiting for a runner at a race? ETA tells you the clock time they reach you, with a live countdown that carries on to the Lock Screen, up to three alerts, and on iOS 26 and later an alarm that rings even on silent. Tap when they arrive and the leg is saved with the pace they really ran. FREE • Four linked calculators: tap any value to edit it, tap a unit to switch between miles and kilometers. Every row keeps its own units. • Race distances built in: 400 m, 5k, 10k, half-marathon, marathon, and ultras from 50k to 100 miles. • Share card: send your distance, time and pace as an image. • Make it yours: light or dark, eight accent colors with matching app icons or the Multicolor theme that gives distance, time, pace, and speed each their own color, reorderable sections, and the Classic interface if you prefer it. • Accessibility: VoiceOver, Voice Control, Dynamic Type, Sufficient Contrast and Reduced Motion. • All calculations work offline. Seven languages. PRO (one-time purchase, no subscription) • Splits: plan even, negative or positive splits at any interval from 100 m to 10 miles, by halves, thirds, quarters or fifths, or an interval of your own, then export the table. • ETA: made for relay exchanges and race spectators. Each runner gets a card with the arrival clock time, a live countdown, estimated progress, up to three alerts and a note. On iOS 26 and later, an alarm rings like an alarm clock before they arrive, even on silent and in a Focus, with Snooze. The countdown also runs on the Lock Screen, in the Dynamic Island and as a badge on the main screen.

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.
