How to Use this Calculator
Enter a pair of values (distance / 500m split / cumulative time), and click the relevant calculate button to return the third value and watts.
Example: Enter values in the distance (2000) and 500m split (1:50) fields, and click Calculate time to return your time (7:20).
Formulas Used
distance = (time/split) * 500
split = 500 * (time/distance)
time = split * (distance/500)
watts = 2.8/(split/500)³
