How to Use Run Training Paces Calculator
The Run Training Paces Calculator analyzes your recent race performance to provide personalized pace recommendations for various types of runs, including easy, marathon, tempo, interval, and repetition paces. It translates your race potential into actionable training zones, helping you target each session at the right physiological adaptation.
What It Does
Use the calculator with intent
The Run Training Paces Calculator analyzes your recent race performance to provide personalized pace recommendations for various types of runs, including easy, marathon, tempo, interval, and repetition paces. It translates your race potential into actionable training zones, helping you target each session at the right physiological adaptation.
This tool is ideal for runners of all levels – from beginners aiming to build endurance without overtraining, to experienced athletes looking to refine their speed work and prevent plateaus. It's also invaluable for coaches setting objective training targets for their athletes, ensuring every session contributes effectively to race readiness.
Interpreting Results
VDOT is the single fitness number the rest of the plan hangs on; a higher value means faster training paces across the board. Read the input pace per km as a sanity check that the race time you entered matches the effort you actually ran, since a mistyped time inflates or deflates every prescribed pace.
Input Steps
Field by field
- 1
Enter inputs
Enter distance with realistic baseline assumptions before moving to sensitivity checks.
- 2
Enter inputs
Enter race time minutes with realistic baseline assumptions before moving to sensitivity checks.
- 3
Enter inputs
Enter the seconds portion of your race time. A few seconds either way barely moves VDOT, so an estimate from a recent hard effort is fine if you have no exact race result.
Feed in a race from two different distances; if the VDOT values disagree, the slower one usually reflects your weaker event and a more honest training base.

A 50:00 10k maps to a VDOT of about 40, slightly above the 38.3 from a 25:00 5k, which is the expected pattern when a longer race reflects a marginally stronger aerobic base.

Dropping the 5k from 25:00 to 22:00 raises VDOT from about 38.3 to 44.5, and every prescribed training pace tightens accordingly.
