In February 2004, three young people were sent to train at the organization EarthCorps, in Seattle, United States, to gain skills on trail construction and volunteer management. They returned just in time for the 2004 season with GBT. With them came two qualified experts from EarthCorp], who spent three months helping with work on 15 projects. 2004 was a significant year, as Rotary International "adopted" 100 km of trail, and Baikal Plan in Germany joined up with GBT, sending 100 volunteers to help with trail construction. Also in 2004, GBT was incorporated as a non-profit organization, allowing it to apply for grants. This is how it became the interregional public organization "The Great Baikal Trail."
