第10回東日本ハーフマラソン・8km＆駅伝 2026

The East Japan Half Marathon, 8km & Ekiden takes place within Sagami General Depot in Sagamihara, Kanagawa, a U.S. military installation typically inaccessible to the public. Participants can select from three distances: a 21.0975 km half marathon, an 8.348 km run, and a 16 km ekiden relay. The half marathon has a three-hour time limit, and the 8 km race has a 70-minute limit, accommodating both those aiming for a fast time and individuals seeking a less demanding race day with companions. The route consists of flat asphalt roads within the base, featuring minimal elevation changes, which facilitates consistent pacing and is conducive to runners targeting a personal best. The half marathon is limited to 4,000 participants, the 8 km race to 1,000, and registration is on a first-come, first-served basis. Sagamihara markets itself as a space city, and the event incorporates space-themed decorations, enhancing the unique atmosphere of running through a normally restricted area. The event also offers American food choices and merchandise sales, contributing to a base festival ambiance alongside the road race.
