How it works

qualified if marathon time ≤ B.A.A. standard for your age band and gender

This page keeps the calculation centered on one relationship: qualified if marathon time ≤ B.A.A. standard for your age band and gender. Inputs are normalized before the final display, which keeps mile, kilometer, pace, speed, or zone outputs from drifting because of rounding. Use the number as a consistent model output, then layer in terrain, weather, recovery, and race execution. Keep the fixed reference values in view: 60, 2026, 18–34, 2:55, 00, 3:25, 35–39, 3:00.
