Snow Biking in Japan

cycling training on snow with road racing bikes with studded tires

Mt.Tokachidake (Mt.Tokachi) 180

Temperature: minus 26 degrees Celsius in the KTV (katabatic valley) and minus 17 degrees Celsius at the Tokachidake Hot Springs (Tokachidake Onsen).

Maximal velocity: 72.6km/h

The temperature went down because of a radiative cooling. There were traces of other bikes on the snow. He used ski goggles with heating lenses on the climb as the temperature was low. The brake levers became heavy as the grease and the oil congealed. He met two other cyclists at the summit, who had left the traces. After the interval training at the summit, he descended. He received a first-degree frostbite at the surface of the abdomen during the descent. The equipment against the cold must be insufficient.
