Marathon Training Pace Zones Calculator
Get suggested easy, tempo, and interval training paces from your goal marathon pace.
Assumptions used in this calculation
- General guideline: Uses commonly cited offsets from goal marathon pace as a training guideline, actual training zones should be adjusted based on your fitness, race history, and a coach's input.
About this calculator
Training plans typically prescribe workouts relative to goal marathon pace, telling you to run 'easy pace' or 'tempo pace' without spelling out what that means in minutes per mile, which leaves runners either guessing or digging through pace charts mid-run. This calculator takes your goal marathon pace and applies the commonly cited offsets, roughly 60-90 seconds slower per mile for easy runs, 10-20 seconds faster for tempo efforts, and 40-50 seconds faster for interval work, to produce concrete target paces for each training zone. Instead of eyeballing effort or running everything at the same pace, which is one of the most common training mistakes, you get specific numbers to aim for on your watch. It's a guideline based on your goal, not a physiological test, so treat the output as a sensible starting point to refine against how your training actually feels.
Worked example
Goal pace 9:00/mile
Result: Easy ≈ 10:15, Tempo ≈ 8:45, Interval ≈ 8:15
