The Gunma Marathon, held annually in Maebashi, Gunma Prefecture, Japan, features a certified 42.195 km full marathon that winds through the city along the Tone River and finishes at Shoda Shoyu Stadium. Since adding the full marathon in 2015, the event also offers a competitive 10 km race and a more relaxed Riverside Fun Run, though the latter has occasionally been omitted due to health or logistical concerns. The course is well-supported with water stations every 3 km, aid zones serving local snacks, and unique split-time certificates, making it a standout autumn race for both serious and recreational runners.
