What is Half Marathon Pace?

Pace in running refers to the time it takes to cover a specific distance. For the half marathon, knowing your pace (typically expressed in minutes per mile or kilometer) allows you to predict your finish time and to train effectively. It also enables you to monitor your performance during the race and make adjustments as needed.

How to Use Our Half Marathon Pace Calculator

Our tool offers three powerful calculation options to help you train effectively:

  • Calculate Pace: Enter your target finish time and distance to determine your required pace.
  • Estimate Finish Time: Input your average pace and the distance of a half marathon (13.1 miles or 21.1 kilometers) to estimate your finish time.
  • Calculate Distance: If you have a set time you're willing to run and a target pace, find out how far you can run.

All calculations are presented in both miles and kilometers for your convenience.
