, cycling through Far Eastern Russia, Mongolia, China, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, Turkmenistan, Iran, Oman and United Arab Emirates.
While in Iran, Dimitri was able to secure all of the proper permissions from the Iranian and Omani authorities so that he could be allowed to swim and kayak across the Strait of Hormuz, which he accomplished in January 2016, and therefore allowing him to continue his human powered circumnavigation of the world.
As of November 2016, Dimitri and Gulnara are currently finalizing their Saudi visas to be allowed to cycle through the Kingdom of Saudi Arabia on their way to Jordan, Egypt and further to the southwestern coast of Africa, where the row across the Atlantic Ocean will begin.
