About the 45KM Course

Phase 1: Blanche Takayama Ski Resort (Start) – Omine Peak – Echo Valley Ski area
From the start, you will head to Omine Peak at an elevation of about 400m. Try not to over-exert your legs – even at a walking pace, it will take about 40 minutes to reach the peak. Once you get to the top, you’ll head down the “Villa Site Road” toward the Echo Valley Ski area. At around the 9KM mark there will be a water station.

Phase 2: Himeki-daira – Nagato Ranch (Aid Station 4)
From the water station in Himeki-daira, you’ll run along rural forest roads and a small water channel. At the 24KM mark, you’ll close in on Nagato Ranch. Aid Station 4 is located in front of the terrace house on the way to the ranch.

Phase 3: Nagato Ranch – Daimon Pass (Aid Station 5)
After Nagato Ranch, you’re ready for the second half of the course! On the way to Daimon Pass, enjoy a beautiful view of Mt. Asama and Mt. Tateshina. There will be a small gradual incline towards the 29KM mark, then a nice downhill ride to Daimon Pass (AS5) at the 32 KM mark.

Phase 4: Daimon Pass – Blanche Takayama Ski Resort (Finish)
From Daimon Pass (AS5), it’s a tough climb to the +1,800m ridge line at the 39KM mark. From the ridge, you might be lucky enough to see Mt. Fuji, the Northern Alps, Mt. Ontake, and the Yatsugatake Mountains. The best part of the course starts here at the peak (1,838m) and towards the tail-end of the course at the 40KM mark. After that, it’s a manageable descent back to the finish!
