The route is as follows.

  • From start in Biysk, following the Chuysky trakt, to Kosh-Agach.
  • From Kosh-Agach back to the north, through Ust-Sema to the bridge that crosses the Katun river near the Biruzovaya Katun resort.
  • Over the bridge, then to the Aya village.
  • From Aya village to Altayskoye village.
  • From Altayskoye through Nizhnekamenka, Rossoshi, and Starobelokurikha to the Belokurikha-2 resort.
  • From Belokurikha-2 to finish in Biysk.

The route is 1200 km long, the total ascent is approximately 10 km.

There may be minor changes to the route. Should they happen, we will announce that.

We have prepared the interactive track of the route that can be downloaded in various formats for use with electronic navigation devices.

Roads and terrain

All roads on the route are asphalted, and the average quality of surface is good. Roadworks are possible; usually one lane is closed for repairs and the traffic goes through the other one. We will notify riders about coming roadworks.

The valley of Katun from Gorno-Altaysk (Горно-Алтайск—for your convenience, we provide Cyrillic names that you may see on the road signs) to Ust-Sema (Усть-Сема) is a popular resort. There are many villages and camping grounds there, and hence the traffic may be significant.

On the figure below you can see a schematic altitude profile of the route. Riders will have to climb over three mountain passes (two of them—twice, once on the way to the south and once on the way back), ascent onto the plateau of the Chuya steppe, and climb the serpentine to the Belokurikha-2 resort.

Numbers refer to: 1. Seminsky pass. 2. Chike-Taman pass. 3. Kosh-Agach. 4. Chike-Taman pass. 5. Seminsky pass. 6. Biruksinsky pass. 7. Belokurikha-2.

The Seminsky pass is 1717 m above the sea level. The northern ascent is 9 km long, and the southern one is 11 km long, both without a serpentine. The ascent is approximately 500 m on both slopes, with the average gradient about 7%, and local gradients up to 10% on the northern slope and up to 12% on the southern one. The pass is close to the tree line. Air temperature may differ a lot between daytime and nighttime.

The Chike-Taman pass is 1295 m above the sea level. Both slopes are serpentines about 4 km long with average gradient of 10%.

The Chuya steppe is a mountain valley in the upper part of the Chuya river. The altitude near Kosh-Agach is around 1800 m above the sea level. The major part of the climb goes along the river and looks like a series of short climbs and descents, by which the road gradually goes higher and higher. Some local gradients are 12% and steeper. The Chuya steppe is slightly undulating plain; the climate there is rough.

The Biruksinsky pass is 600 m above the sea level. The climb is around 300 m high and 20 km long, starting in the Aya village. The pass has a "false" saddle and a short and steep (12%) piece just below the highest point.

The serpentine between Belokurikha village and Belokurikha-2 resort is 7 km long, with the total ascent of about 400 m. The highest point is approximately 700 m above the sea level.


There will be approximately 10 controls, including the start one. Riders will need to check in every time they pass the control.

Food and drinks will be available at all controls. Some places will also feature showers and places for sleep. There will be one bag drop.

We will describe the controls on this page when we have the exact list of them.
