No Moku score yet. Dates and details come from each race's official page, with any race reports we have read.

About these ratings

Races are scored out of 5 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 38 of 119 scores are thin evidence: fewer than 5 sources each (dashed score, marked provisional). Show only races with 5+ sources. 1 races run a non-standard course and are flagged.

9 races are paused or discontinued and hidden until you turn off “Active races only” in All filters.
