About RunPerform
RunPerform is a set of free running tools: a pace calculator, a race time predictor, a VDOT calculator, printable pace charts and pace bands, and beginner training plans. Everything works in kilometres and miles.
How we make the numbers
Paces are time divided by distance. Predictions and training paces use published methods: the Riegel formula (American Scientist, 1981) and the Daniels and Gilbert equations (Oxygen Power, 1979). Each tool shows its formula and source. The training plans are our own and follow common principles: a slow build, one long run a week, easier weeks and a taper.
