みなかみ１００(100K/60K/25K)

Minakami 100 is a trail running series held at Norn Minakami Ski Resort in Minakami Town, Gunma Prefecture, offering 100 km, 60 km, and 25 km distances. The venue is accessible via the Kan-Etsu Expressway at Minakami IC, with a free shuttle bus service available from Jomokogen Station. It welcomes both novice and seasoned trail runners, featuring a modest field typically numbering in the low hundreds, avoiding a crowded start. The courses traverse the ski resort grounds and adjacent mountain roads, with numerous runnable forest paths and minimal hazardous terrain, making the longer distances suitable for a first ultra. Participant feedback highlights a welcoming, intimate atmosphere: staff actively foster a positive environment, runners interact and offer encouragement on shared or overlapping sections, and the finish line has featured pork soup, instant noodles, and rice balls. Despite its approachable nature, the event retains some challenges, such as past reports of unclear course markings near the Mt. Azumaya descent and an aid station heavily stocked with drinks after Mt. Oone, necessitating runner vigilance even on less demanding terrain.
