【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24日大会 2026

PSS Imperial Palace Health Running is a small morning race-and-training series held at the clock tower within Sakuradamon at Tokyo’s Imperial Palace. The format includes 5 km, 10 km, 20 km, and a 20 km relay, with modest entry fees and fields limited to about 100 runners per solo event plus a small relay field. PSS Inc. organizes it as both a competition and a practice session, using manual timing with a stopwatch and printer instead of a chip-based system. The course begins and ends at the same location, consisting of laps around the Imperial Palace. This allows runners to concentrate on their pace, splits, and distance without distraction. The event accommodates beginners, club runners, marathon trainees, and relay teams, and is noted for its utility as structured long-run practice, offering an alternative to solo training. The rules are notably flexible: late arrivals, same-day registration, same-day event changes, early finishes with recorded distances, and even custom distances can be accommodated. Time checks are still in place for longer races, and the event is canceled in rain or snow, but the organizer describes it as Japan’s most relaxed race.
