The PSS Imperial Palace Health Running event is a small race and practice session held on the Imperial Palace running loop in Chiyoda, central Tokyo. It provides 5 km, 10 km, 20 km, and 20 km relay options. Beginners and experienced runners participate in the same morning setup. The participant numbers typically range from 100 to 499, giving it the feel of an organized training day rather than a large city road race. The organizer, PSS Co., Ltd., presents it as an accessible Imperial Palace event and states its goal is to be the foremost race around the palace in Japan.
The start and finish are located near the clock tower inside Sakuradamon Gate, a common meeting spot for runners using the palace loop. The 5 km and 10 km races have two-hour time limits, while the 20 km and relay divisions allow two hours and 45 minutes, with checkpoint cutoffs for those completing the longer distances. The race emphasizes flexibility: late arrivals, same-day entries, same-day distance changes, stopping early without a DNF, and even custom distances like 15 km are permitted. All participants receive an award, typically via email, as the organizer determines awards before the event begins. Participation gifts may include a sports drink, an izakaya meal ticket, and a magnetic chip. Participant feedback highlights its affordability, ease of entry, utility for fitness checks, and suitability for long training runs that are difficult to complete solo.
