Understand your numbers

Clear explanations of units, cumulative times, rounding and printed pace bands.

Pace vs Speed

Understand time per distance and distance per hour, with a worked 5:00/km, 12 km/h example.

Use the exact mile conversion and keep distance markers separate from pace-unit labels.

Tell elapsed time from segment time, locate halfway and finish, and check a subtraction example.

See why rounded pace labels must not be added repeatedly, and how cumulative rows preserve the exact target.

Read a printed band’s distance markers and cumulative times, and check its title, units and finish before using it.

Choose A4 or Letter, use 100% print scaling and check the 100 mm calibration line before cutting your band.

Calculate completed laps and the remaining distance without rounding a partial lap into a full one.

Understand a first-half time percentage and calculate two exact half times from one target.
