Estimate Ironman qualifying slot allocations based on age group starting numbers (system prior to 2026).

  • Set the number of slots to be allocated to men/women or all athletes.
  • Specify the total number of starting athletes.
  • Select an average starting distribution based on numbers at races over the last 5 years.
  • Fine tune the stat numbers by adjusting individual age groups

The legacy Ironman slot allocation algorithm is applied to settings as you adjust them to determine the qualifying slot allocation that would result.
