This calculator will help you estimate the general pace ranges you should be running based on your current fitness, and will help you calculate your paces for an upcoming goal race!
​
PLEASE NOTE: This calculator is NOT a guarantee; it's intended to provide reasonable "guesstimates"! Additionally, the marathon "equivalent" is on the aggressive side; use the FiveThirtyEight Marathon Calculator for a more realistic guesstimate based on multiple factors and inputs.
