Analysis
What the numbers actually say about triathlon — one piece at a time, method and sources at the bottom of each. No categories, no tags, just the list.
The bike is where the time is. The run is where the day is decided.
665,769 amateur finishers across 394 full-distance races: the bike is the discipline most connected to the other two, the run is where finish times spread out, and transitions are worth more than twice their length.
