We boxed up the bikes and bags and boarded a flight from Perth, Australia to Ho Chi Minh in Vietnam – our starting point in southeast Asia. As soon as we stepped off the plane in Vietnam our clothes stuck to our bodies like we had just stepped inside a sauna dressed as Santa Claus, beads of sweat instantaneously rolling down our face. This was going to be a completely different type of challenge to crossing Australia.

After reassembling the bikes, spending a few days acclimatising to the heat, visiting the Chu Chi Tunnels, The War Remnants Museum and the villages along the Mekong Delta, we hit the road.
