Weihai's dramatic coastline delivers one of the hillier courses of the season, with climbing on both the bike and the run.
2 km sea swim in the sheltered bay at Weihai on the Shandong peninsula.
80 km on closed coastal roads with significant rolling climbs above the Yellow Sea — a genuinely hilly course.
18 km undulating coastal run with sea views and several short climbs.
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.
