There are thousands of marathons around the world, literally from pole to pole. But the Bhutan marathon is definitely special. Run up the valley from Thimphu to the edge of Jigme Dorji Wangchuck National Park and back. the entire race is run at around 2500-3000m. Not as high as the Everst marathon, but it still takes some getting used to. This is the first internationally sanctionted version of the event, September 7, 2008.
