The oldest IRONMAN in North America — mountain climbing, an Olympic-village finish and legendary local support.
Two-lap cable-assisted swim in Mirror Lake — clear, cool and one of the easiest swims to sight in the sport.
Two hard laps in the Adirondacks: the fast Keene descent, the long grind back up through Wilmington and the Papa Bear climb into town.
Two-lap run out to River Road and back up the brutal hill into the Olympic Oval finish.
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.
