Concept
Current race pace
The pace a runner's current fitness can realistically sustain for a specific race distance under suitable conditions.
Why distance matters
A sustainable pace for 5K is not sustainable for a half marathon. Race pace always belongs to a particular distance.
How it is estimated
Recent races, controlled tests, and repeatable specific workouts provide evidence. Calculators can translate that evidence but cannot remove uncertainty.
Why it changes
Training, fatigue, terrain, weather, and race execution all influence the pace that is realistic on a given day.
How to use it
Base workouts and race plans on conservative current evidence, then revise after meaningful new results.
Common misconception
Current race pace is not the same as a desired goal pace or the fastest pace seen briefly in training.
