A flat, fast late-summer Canadian iron-distance race on closed parkways in the capital — a strong first-full or PB target.
Two-lap swim in the Ottawa River off Mooney's Bay, sheltered and typically wetsuit-legal in August.
Fast, largely flat three-lap course on the Ottawa River Parkway with wide closed roads and only gentle rollers.
Flat four-lap run along the Rideau Canal and Dow's Lake pathways, shaded in places and heavily spectated.
Actual monthly averages from the last 3 years (Open-Meteo). Real race day may vary.
Water temp uses athlete-reported values first, then official race data, then the marine archive (sea swims, measured at the nearest offshore point). Values tagged est. are modelled from recent air temperature for lakes and rivers, where no observational data exists.
