Tired of juggling apps, websites, and bookmarks to plan your race training? CalcuRun is an all-in-one solution — completely free, with no ads and no accounts. Newly redesigned in version 3.0 with a chronograph-inspired look and a dot-matrix display, CalcuRun helps you predict race times, plan splits, and dial in your workout paces. Features * Input a recent race or time trial and get accurate predictions across common race distances. * Use the "Other" race distance for non-standard events. * View splits for each race, in kilometers or miles. * Get workout paces based on your predictions. * Use the Calculator to plan an individual race — input a time or pace and calculate the other. * Sync your saved races and predictions across your iPhone and iPad with iCloud. * Redesigned iPad layout with a sidebar that takes advantage of the bigger screen. * Choose between the new dot-matrix display font or the system monospaced face. * Learn more about how the calculations are performed. Most importantly, your data is private. Calculations run entirely on your device.
