Why every runner needs a pace converter

Treadmills show mph, road races mark km, track workouts measure 400 m repeats and Strava gives min/km — every device speaks a different dialect of pace. One converter unifies them all.

Pace per 400 m is especially useful for interval training: 5K race pace runners often target 90-95 second 400s, marathon pace runners about 110-120 seconds.
