400m Potential Calculators (UPDATED 5/23/18)

This test is designed to measure anaerobic capacity. All you have to do is run a 100m, wait 5min, and run a 400m. Enter the times in the appropriate spots to find the value. The aim is always to reduce the 'drop off' time by increasing anaerobic efficiency. A top female 400m athlete will have a ‘drop off' time of around 0.7 seconds. You should aim for a <2 value.

Frank Horwill's 40 yard test is used to predict an athlete's potential 400 meter time.

I modeled this off of Brian Mackenzie's data in his Sprint Prediction Calculators. For this one you need to know your 100m time. It will also give you your 200m as a bonus.

Estimation based off 45 professional athletes who run the 100m, 200m, and 400m.

Estimation based off the classic 800m estimate using a 400m PR.

Estimation based off the classic 400m estimate using a 200m PR.

Estimation based off Sam Harding's formula for an 800m using a 400m PR.
