Threshold Running Heart Rate Training Zones

By MyProCoach

Use this simple calculator to estimate your running training zones based on your THR (Threshold Running Heart Rate). You can then print your results or download as a PDF. We hope you find this useful!

What is your THR? It is your current average heart during a 1 hour race. If you don’t know yours, you can do this field test.

Planning Your Off-Season

You can start our Off-Season (Fitness Maintenance) plans anytime you like.

They’re designed to help you maintain a good level of fitness when you’re not specifically targeting an event, such as, during the off-season, or anytime you’re taking a break from racing.

Planning For Your Event

For the best outcome, input the date for your “A” target race and the tool will default to a plan that will fill that gap nicely. If you want, you can then adjust the plan length to start it on a different day.

Note that you can still work in other, smaller races during your plan too!

The longer plans start easier and progress more gradually. This has a bearing on the difficulty level you choose. For example, a 12-week plan starts off at a higher level than a 36-week plan because with 12 weeks left there’s not as much opportunity to build up slowly.
