About these ratings

Races are ranked by an overall score out of 5, built from racer reviews and race reports, on the race itself, swim, bike, run, conditions and travel. 5 is always the better end. How we rate

Full distance course: 3.8 km (2.4 mi) swim, 180 km (112 mi) bike, 42.2 km (26.2 mi) run.

Reports on full-distance races are scarcer, so 1 of 4 scores are thin evidence: fewer than 5 sources each (dashed score, marked provisional). Show only races with 5+ sources.
