Race Across The World

Five teams set off from Mexico City -- a gargantuan metropolis and the largest Spanish speaking city in the world -- in a race to reach the most southerly city in the world, Ushuaia in Argentina. The first checkpoint is Copan Ruinas in Honduras.

The five teams head out of Copan Ruinas in Western Honduras to their next checkpoint -- Panama City. It's a journey that will see them travel across vast swathes of Central America, passing through Honduras, El Salvador, Nicaragua, Costa Rica and Panama.

Setting off from Panama City, the remaining four teams take to the Caribbean Sea, but there are complications when a state of emergency is declared at their next checkpoint, and they are forced to change routes mid-race and head to Villavieja, Colombia.

As the race approaches the halfway mark, the four teams battle the extreme altitudes of Peru when they head to Puno, a city on the edge of the highest and largest lake in South America, Lake Titicaca.

To reach the next checkpoint in Cafayate, Argentina, the four teams must choose to travel through either Bolivia or Chile. But an unstable political climate in both countries puts everyone's journeys at risk, and emotions are pushed to breaking point.

The teams must travel 3,600 km east from Cafayate, Argentina, to the next checkpoint on the island of Ilhla Grande, Brazil, while dealing with an ever-dwindling budget and contending with a brand new language.

With two teams at the checkpoint in Brazil, the remaining teams are engaged in a frantic race to avoid finishing the leg in last place. Depleted budgets come into sharp focus as the teams head to the next checkpoint in Mendoza, Argentina.

After 21,000 kilometres, two continents and 17 countries, the teams embark on the final leg of their epic journey to the finish line of Ushuaia, Argentina, and the racers are rocked by the departure of one team from the race.

The race from Mexico City to Ushuaia, Argentina, may be over, but the drama is now unfolding, as all five teams reunite for the first time to reveal their fascinating insights into their different strategies and individual experiences.
