The idea of the marathon is the similar start of Russian, Ukrainian and Belorussian athletes from Moscow, Kiev and Minsk respectively to reach the Three Sisters Memorial located in the tripoint of three states' borders. The next race took part in 2016, but without Erokhin, who was preparing for his next ambitious project, running around the Baikal Lake. The distance was from 1400 to 2000 km (regarding from occasions), the term was 50 days. Ultratrail running Baikal was created by Erokhin as a humanity media action: he expected to attract public attention to Baikal and the Transbaikal region, to its ecological problems and perspectives of health resort and recreation zone. Moreover, Erokhin positioned his race as a Wiki-expedition during which he would gather encyclopaedic materials and take photos of different objects. These photos would be given to Wikimedia Commons and used as illustrations of Wikipedia articles dedicated to Baikal and the region. On July 1, 2016 Erokhin moved by ferry from the village Listvyanka, Irkutskiy District to Port Baika,l where he began his race. He had consultants, financial support and an escorting group with a cat and catamaran. Another extreme sportsman, Alexander Soldatov, took part similarly with Erokhin, using a kayak. However, most of his race Erokhin spent alone with a map, compass and satellite phone. He had a snack only once a day and he could meet the group only in the evenings. He spent nights at touristic bases or camping places. The progress of Erokhin's expedition was available on the Internet at the site Iridium360. The main difficulty of the route was the unstable conditions including temperature drops, landscape variability and the degree of terrain habitability (from fully populated districts to totally wild at the eastern part of the shore). A runner also had to be ready for force-major situations: swamps, gnats, wildfires and wild animals. During a couple of days Erokhin had to move along the burning forest, and twice had to drive a bear away using flares. In an interview he noticed that the Baikal trail had the same difficulty as Marathon des Sables in Sahara (in some aspects it was even harder). On July 28 Erokhin went 24 km from Kotelnikovsky Cape and spent a night in a winter hut. In the morning he woke up with body temperature over 40 °C.
