In a frenetic race across the world, travellers can choose any route they like - but no flights or phones are allowed. On the trip of a lifetime, which pair will finish first?

The teams enter south east Asia, starting the third leg from Vietnamese capital Hanoi. They must race over 2,000km through Vietnam and into the Kingdom of Cambodia to reach Phnom Penh.

The teams are starting from the third checkpoint in Phnom Penh, Cambodia, and must travel 1,400 kilometres through Thailand, one of the most visited countries in the world.

The teams must navigate the full length of Thailand to reach the next checkpoint - Koh Phi Phi - an archipelago of islands immortalised by the Hollywood blockbuster movie The Beach.

After the tranquillity of the islands of Koh Phi Phi, the teams now face a giant leap into the unknown, leaving Thailand behind to embark on a 2000km journey to the Indonesian island of Sumatra.

The teams must travel through the populous Indonesian island of Sumatra, where they will endure an ad-hoc transport system, limited accommodation options and virtually zero English spoken.

Twelve minutes is all that separates the first two teams as they embark on the final leg of their Race Across the World from Jakarta to Lombok.
