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
Olympic course: 1.5 km (0.9 mi) swim, 40 km (24.9 mi) bike, 10 km (6.2 mi) run.
Reports on Olympic-distance races are scarcer, so 3 of 7 scores are thin evidence: fewer than 4 sources each (dashed score, marked provisional). Show only races with 4+ sources. 1 of these races set their own distances, and each race page lists the real course.
1 race is paused or discontinued and hidden until you turn off “Active races only” in All filters.
