【猛暑対策】ピーエスエス皇居健康ラン8月9日大会 2026

PSS Imperial Palace Health Running is a low-cost summer race around Tokyo’s Imperial Palace, with the start and finish near the Sakuradamon clock tower. Runners can choose 5 km, 10 km, 20 km, or a 20 km relay, with each lap measuring about 5 km. PSS Inc. organizes the event, and the field is small by big-city standards, usually around 100 to 499 people. Entry is simple and cheap: 1,000 JPY for an individual runner and 4,000 JPY for a relay team. The race is unusually loose about logistics. Same-day entry is allowed, late arrivals are accepted, and runners can change distance on race day or even during the run. Someone who feels tired can stop early and still have the distance recorded; someone feeling good can add laps. The 20 km race is four laps, though runners must start the fourth lap by 10:15 AM, and 10 km runners must pass 5 km by the same time. Timing is manual, using a stopwatch and printer, which fits the organizer’s own description of it as “Japan’s most relaxed race.” It suits beginners trying the Imperial Palace loop and experienced runners who want an inexpensive supported pace run or long run without doing it alone.
