After Dushanbe we rode to Samarkand, another beautiful mountain road. Less fun was the tunnel at the top of the pass, pitch dark and not ventilated. Like most cyclists we hitched a ride with a kind Tajik driver, but those 10 minutes in his van were the scariest shit ever. We should have filmed it but we were so terrified we couldn't move. We took a pic of the tunnel exit, the fumes are much worse inside, couldn't see shit.
