Good to know

The calculation runs in your browser. Use consistent units in fields with no explicit unit.

Calculation method

Pace is elapsed time divided by distance. Finish time extrapolates constant pace. Split rows use the selected distance unit and accept up to 100 rows.

p=td,v=dtp=\frac{t}{d},\qquad v=\frac{d}{t}
