令和8年8月8日「オール”8”」皇居外苑記念ジョギング大会 2026

The All 8 Imperial Palace Outer Garden Memorial Jogging event begins at Tokyo's Sakuradamon Clock Tower, within the Imperial Palace Outer Garden. This road running event centers on the uncommon all-8 date pattern in the Japanese era calendar; the number in the name highlights its purpose as a commemorative run, distinct from a standard palace-loop jog. The race is a fixture on the Kanto running calendar, utilizing the Imperial Palace area. This location is well-known to runners for its wide roads, central accessibility, and convenient meeting spots. Organizers present it as an occasion for health and camaraderie, welcoming local residents, domestic participants, and international visitors to run together. It is also part of a planned sequence of number-matching races, with future events scheduled for subsequent dates featuring repeating numbers.
