Both calculators run independently β change the inputs on either side to compare results.
Running
VO2 Max Calculator
Estimate your VO2 max (maximum oxygen uptake) from a timed run by combining distance, time, and age into a Cooper-style empirical formula. Use it as a benchmark for cardiovascular fitness and to track aerobic improvement across a training cycle.

Running
Running Economy Calculator
Calculates a running economy score that reflects how efficiently you convert aerobic capacity into race speed, accounting for VO2 Max, pace, body weight, and experience. Useful for comparing training adaptations over time.
