IRONMAN / 70.3 Stats

IRONMAN / 70.3 result rows stacked by gender then age group (M cool / F warm). Green line: unique canonical athletes per year.

IRONMAN / 70.3 distinct event_ids stacked by host country (ISO 3166-1 alpha-2). Shows how the global footprint grew year by year and which countries host the most races.

Canonical athletes (deduplicated) who raced IRONMAN / 70.3 at least once that year, stacked by residence country. Japanese prefecture codes (JP-XX) collapse to JP. Long-tail countries fold into OTHER.

Results with status = finished, grouped by distance code.

Events ranked by total result rows across every edition.

Finish rate per distance category (finishers / starters; DNS is excluded from the denominator). Categories with fewer than 50 starters are excluded.

Median (50th percentile) of finishing times across all finishers. Year × distance cells with fewer than 30 samples are dropped.

Bike-leg median (distance_km ÷ lap_seconds) restricted to the Top 10 overall finishers per race. The mid-pack median is dominated by fitness variance and washes out the equipment signal; the pointy end is where aero road / disc brakes / TT bikes / latest carbon wheels actually appear. Cells with fewer than 10 samples and obvious data-entry outliers (below 15 km/h or above 65 km/h) are dropped.

Race count per canonical athlete (deduplicated). Birth year shown as BY for disambiguation.
