How we estimate your 10K
We combine known marks with a distance fatigue exponent plus volume/experience adjustments. With only zone 2, we estimate race pace relative to your aerobic base.
Indicative estimate based on pace and fatigue models. It does not replace a plan with real history, recent tests, or race-day conditions (heat, elevation, HYROX penalties).
