The race to Lombok is well underway and less than five hours separate the teams. Leaving Nara City, they must cross their first border into South Korea to reach the second checkpoint in Sokcho.

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.

The five intrepid teams reunite in London to look back at their 51-day thrilling adventure through some of the most beautiful, populous and remote places on the planet.
