【猛暑対策】ピーエスエス皇居健康ランニング令和8年10月11日大会 2026

This PSS Imperial Palace Health Running event is a small October race and practice session held at Sakuradamon within Tokyo’s Imperial Palace grounds. Participants can choose from 5 km, 10 km, or 20 km distances, with an additional 20 km relay option for teams. The individual races are priced affordably at 1,000 yen, while the relay costs 4,000 yen. With a limit of approximately 100 runners per category and 25 relay teams, the event offers an atmosphere akin to an organized training day rather than a large-scale competition. The 20 km and relay races commence in the morning, preceding the 5 km and 10 km events, and all races conclude at their starting point. Timing is conducted manually with a stopwatch and printer, and all participants receive an award. The course follows the well-known Imperial Palace loop, providing a suitable environment for runners seeking controlled pacing and straightforward lap monitoring. Feedback suggests it is a valuable option for marathon preparation, long-distance practice, and assessing current fitness during an off-season period. PSS characterizes it as Japan’s most relaxed race, a sentiment reflected in its flexible rules: late arrivals are accommodated, same-day entries are permitted, participants may switch events on race day, and even custom distances like 15 km can be accepted. Should a runner stop mid-race, the organizer records the distance completed rather than marking it as a withdrawal. However, cutoffs are in place for longer distances, including a lap requirement for the 20 km race and a halfway checkpoint for the 10 km. The organizer reserves the right to cancel the event in adverse weather or difficult social conditions, with no monetary refund, though entries can be deferred indefinitely.
