Run to the Sun is a great option for those travelling south: it begins in Hanoi and ends in Danang. Ride through pristine jungle past remnants of the Vietnam War on the Vietnamese section of the Ho Chi Minh Trail. Visit UNESCO World Heritage Site Phong Nha national park, ride the Hai Van Pass (made famous by the BBC’s Top Gear), visit Vietnam’s ancient capital Hue and end your adventure in the beach city of Danang.
