Race Time Predictor Enter one recent result and get finish times for every standard distance from a mile to the marathon. RacePace uses the Riegel endurance model, so a 5K time gives a realistic marathon prediction rather than the same pace stretched across 42 kilometres. Heart-Rate Training Zones Turn your maximum and resting heart rate into five personal zones, from recovery to maximum, so every run targets the right effort. Enter your numbers by hand or import them from Apple Health. Printable Pace Bands Export a clean, wristband-style pace band with your checkpoint times to print and wear on race day, or a full split sheet. Share or print either one straight from the app. PRIVACY RacePace has no accounts, no analytics, no advertising, and no tracking. Your favourites and calculations are stored only on your device. The training zones feature can read your heart rate from Apple Health, but only with your permission, and it is never uploaded or shared. RacePace does not record runs or use your location. It is a calculator and planner, not a tracker. Privacy Policy: https://www.jourjourapp.com/racepace/racepace-privacy/ EULA: http://www.apple.com/legal/itunes/appstore/dev/stdeula
