Worth Knowing
Pace is just time divided by distance, but the reason runners track it obsessively is that small pace changes compound sharply over distance — trimming ten seconds per kilometer saves several minutes across a half marathon. This tool also converts between pace and speed, which is handy for treadmill work since treadmills display speed in km/h or mph rather than minutes per kilometer. For race planning, remember that most people can't hold their short-distance pace over longer events.
