Daniels & Gilbert Formula

This calculator uses the standard formula developed by Jack Daniels and Jimmy Gilbert to estimate aerobic capacity from race performance.
Complex regression formula based on velocity and time

Variables:

VVelocity in meters/minute
tTime in minutes

Example

5K in 20:00

Inputs:

Time:20:00
Distance:5 km

Steps:

  1. 1.Velocity: 250 m/min
  2. 2.Calculate oxygen cost of velocity
  3. 3.Calculate % of VO2 Max sustained for 20 mins
  4. 4.Result: ~49.8 ml/kg/min
Result:
49.8
