Training Pace Calculator

Different workouts call for different paces relative to your race pace.

How the Math Works

The Training Pace Calculator uses offsets from your recent race pace to determine tailored training speeds. For example, an easy pace might be calculated by adding 30-60 seconds per mile to your race pace, while an interval pace could subtract 15-30 seconds. These offsets are applied proportionally to your race distance, ensuring consistency across different race lengths. The formula adjusts dynamically based on your input race time and distance, translating it into precise per-mile or per-kilometer targets for each training type.

Practical Applications

To use this calculator, input your most recent race time and distance (e.g., 5K in 25 minutes). Select your preferred units (minutes/mile or minutes/kilometer), and the tool will generate three paces: an easy recovery pace, a tempo threshold pace, and a faster interval sprint pace. These values help structure workouts—like steady long runs at easy pace or speed intervals at race-pace-minus-offset speeds—ensuring balanced training intensity throughout the week.

Day-to-Day Use

This calculator simplifies daily training by providing science-backed pace targets, reducing guesswork and overtraining risks. Runners can confidently plan workouts, knowing their easy runs won’t compromise recovery and their intervals will push performance effectively. Over time, adjusting these offsets as fitness improves helps track progress and avoid plateaus, making every run purposeful and aligned with race-day goals.

Worked example

5:00/km race pace → easy ~6:15, tempo ~5:20, intervals ~4:45.
