競走
Night start through rhododendron forests and ancient beech groves surrounding a 1,300-year-old hot spring village.
A single continuous loop starting and finishing at Yukemuri Kenkou Village in Yamanaka Onsen. The course winds through the foothills of Mt. Hakusan, traversing dense rhododendron forests, ancient beech groves, ridgeline trails, and river valleys. The first half runs through the night on technical mountain singletrack with significant vertical gain. Dawn breaks around km 45-50 as runners descend from the high points into forested valleys. The second half features rolling terrain through cedar plantations and hot spring villages before the final push back to Yamanaka Onsen.

Between start and CP2, track on UTMB Live and enjoy the onsen.
The race starts and finishes here. The start is an electric atmosphere with a night send-off at 6:30 PM Saturday. The finish area will be active from Sunday morning through the 9:30 PM cutoff. There are food stalls, a results board, and a festive atmosphere as finishers come in.
The town itself is compact and walkable. Between the start and finish, spectators can explore the Kakusenkei Gorge, visit Kiku no Yu bathhouse, walk Korogi Bridge, and browse shops along the onsen street. Many restaurants and cafes stay open late during race weekend.
Some UTMB races allow spectators at certain roadside aid stations. Check the race briefing for which checkpoints have spectator access. These are typically at road crossings where the course is accessible by car. Arrive early as parking is limited.
A stunning riverside gorge walk just minutes from the race venue. Natural beauty, a riverside cafe serving matcha, and peaceful forest paths. Perfect way to pass the overnight hours or the long wait during the race.
Download the UTMB Live app (iOS/Android) before race day. Search for "KAGASPA" or "Kaga Spa Trail" and favorite the runner by bib number.
