【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17日大会 2026

The PSS Imperial Palace Health Running series starts and finishes by the Clock Tower inside Sakuradamon Gate, using the Imperial Palace loop in Chiyoda, central Tokyo. This October edition offers 5 km, 10 km, 20 km, and 20 km relay options, with beginner-friendly entry, all levels accepted, manual timing, small fields of about 100 to 499 runners, and unusually low fees: the individual races are 1,000 yen and the relay is 4,000 yen. The 5 km and 10 km races are open to anyone, while the 20 km race is for runners aged 13 and older. Rain, snow, or wider social conditions can cancel the event; refunds are not given, but unused entry fees can be moved to a future PSS event with no expiry. The course is plain and practical: runners repeat laps around the Imperial Palace, so it works well for checking pace, practicing marathon rhythm, or getting through long-distance training that can be hard to do alone. The 20 km and relay fields start earlier than the shorter races, and finish rules include lap cutoffs: 20 km runners need to begin their fourth lap by the set cutoff, while 10 km runners need to pass 5 km by that point. PSS leans into flexibility, calling the event Japan’s most relaxed race: late arrivals are allowed, same-day entry is allowed, runners can change distance on the day, and someone who stops early is recorded for the distance they actually covered instead of simply being marked DNF. Participation prizes include a sports drink, an izakaya meal ticket, and a magnetic chip, and every participant receives an award.
