In Tajikistan you don´t meet a lot of tourists. If you meet some, they are hardly ever just travelling, they are on a quest or challenging themselves. They are cycling through the heat of Central Asia, going by motorcycle or traveling the world in 800 days (http://www.aroundtheworldin800days.com/)
One of them is Andy. A guy from Liverpool, cycling 10,000 miles across 17 countries over 5 months all in aid of the UK’s blood cancer charity, Anthony Nolan. See more at: http://www.cyclingscouser.com
