A tough British 70.3: cool sea swim, punchy Dorset hills and a spectator-packed esplanade run with a leg-sapping fort climb.
1.9 km sea swim in the sheltered arc of Weymouth Bay, typically 16-18 °C with light chop.
Hilly one-lap 90 km bike into the Dorset countryside with steep short climbs and technical descents on narrow lanes.
Three-lap 21.1 km run along the Georgian esplanade with a sharp climb to the Nothe Fort each lap.
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.
