MetricPace – Run Calculator

How fast can you actually run? MetricPace gives you the answer — not from gut feeling, but from sports science. MetricPace bundles the calculators you'd otherwise chase across ten websites, forums and lookup tables into a single app. Built by a coach and masters runner, for runners who take it seriously. No frills, no gamification — every calculation rests on a published model and names its source. YOUR RACE TIME, PREDICTED Enter one result and see realistic times across every distance — from 5K to the marathon. Based on the proven Jack Daniels VDOT system. PACE THAT ADDS UP Pace, km/h, mph, m/s, track splits and target times for 10K, half marathon and marathon. Instantly, precisely, in any unit. CONDITIONS THAT COUNT Elevation, heat and wind cost you time — MetricPace works out how much. And it translates any course to flat, cool, windless ideal conditions so you can compare performances fairly. TRAINING ZONES WITH A FOUNDATION Your zones, anchored to critical speed from the 3-6-12 protocol — not to crude rules of thumb. With optional heart rate ranges. HOW GOOD ARE YOU REALLY? Age grading from the official WMA 2023 tables shows your performance independent of age — and what it would be worth at 25 or at 60. Plus a VO₂max estimate with classification against age and sex norms. FUELLED PROPERLY Calorie demand (ACSM), carbohydrate-fat mix, sweat rate and sodium loss — calculated for both training and racing.
