How is running power converted to pace?

Running power depends on body mass, speed, gradient, and air resistance. The simplified relationship is: power (W) = mass (kg) × speed (m/s) × gradient factor × running economy coefficient. For a 70 kg runner on flat terrain, 250 W corresponds to roughly 4:15/km.

What is a normal running power output for a recreational runner?

A 70 kg runner at easy aerobic pace (6:00/km) generates approximately 170–200 W. At marathon race pace (4:30/km) this rises to 240–280 W. Sub-3-hour marathoners typically run at 280–320 W sustained.
