How the numbers work
Pace = total time ÷ distance. Finish time = pace × distance. Distance = total time ÷ pace. One mile is exactly 1.609344 kilometers. Half marathon and marathon use 21.0975 km and 42.195 km.
Splits assume constant pace on the measured course. Each checkpoint is calculated from unrounded values; displayed times are rounded to the nearest second. A final partial split is included. These are pacing calculations, not predictions of fitness or race results.
