Calculates the “route constant” based on the distance traveled and cumulative elevation gain during a mountain hike.
◎Please enter the cumulative elevation gain and horizontal distance traveled based on your past hiking records or plans.
| Root Constant (Course Constant) |
◎The Route Constant is calculated using the following formula:
Route Constant = 1.8 × Hiking Time (Course Time, h) + 0.3 × Walking Distance (km) + 10.0 × Cumulative Ascent (km) + 0.6 × Cumulative Descent(km)

◎The course time in the above formula is calculated based on the input values using the following equation:
Hiking Time = {Cumulative Ascent (in 100-meter increments) + Cumulative Descent (in 200-meter increments) + Horizontal Distance (in kilometers)} ÷ 4
◎The physical difficulty level indicated by the displayed route constant (course constant) can generally be estimated as follows:

Around 10: Physically easy; suitable for beginners
*Reference: Tarumae Mountain 7th Station – Higashiyama Round Trip: 8.76745
Round trip to the Moiwa Mountain Ski Resort course: 10.8187
Around 20: Suitable for the average hiker
*Reference: Round-trip loop from Tarumae Mountain 7th Station to Mt. Higashi, Mt. Nishi, Mt. Kita, and Ohanabatake Course: 18.323
Round trip on the Teine Mountain Heiwa Falls Course: 22.21785
Around 30: Suitable for experienced hikers on a day trip
*Reference: Loop from Tarumae Mountain 7th Station to Mt. Higashi, Mt. Nishi, Mt. Kita, and Mt. Fubushi: 29.89895
Mt. Yotei: Hirafu Course – Full Circuit of the Crater Rim: 36.8876
40 or older: Difficult as a day hike. Requires planning for at least one overnight stay
*Reference: Mt. Tarumae Nishikioka Course – Mt. Nishi – Mt. Kita – Mt. Higashi (Three Peaks) Round Trip: 42.9416
Mt. Tarumae Nishikioka Course – Mt. Nishiyama – Mt. Kitayama – Mt. Fubushi – 7th Station – Mt. Higashiyama – Mt. Nishiyama: 59.1512
We recommend that you develop your own criteria by comparing this information with individual hiking logs and other records.
