とちぎチャレンジマラソン2026IN栃木市総合運動公園陸上競技場

The Tochigi Challenge Marathon is a February running event held at Tochigi City General Athletic Park Stadium in Kawaradacho, Tochigi. It is designed for a wide range of participants, welcoming Tochigi residents and opening entry to children and adults from all locations. Categories include parent-child, elementary school, junior high school, and high-school-and-up divisions. The event is structured around the stadium, not as a point-to-point road race. Junior high school students and older participants have the option to enter multiple events. Entry fees are modest: the parent-child run costs 1,800 yen, elementary and junior high entries are 1,500 yen. Adult fees vary based on the registration period and whether the runner possesses a Tochitre bib and timing chip. Registration also permits proxy entries, with payment options including credit card, Amazon Pay, or convenience store payment.
