Race Across The World

G Five teams set off from Mexico City - the largest Spanish speaking metropolis in the world - in a race to reach the southernmost city in the world, Ushuaia in Argentina.

G The teams head out of Copan Ruinas in western Honduras to their next checkpoint - Panama City. Having raced hard in the previous leg, leaders Jo and Sam are keen to experience more this time.

PG 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 in the destination of their next checkpoint.

ML As the race to Ushuaia approaches the half-way mark, the four teams compete not just with each other but with the extreme altitudes of Peru - making the sprint to the checkpoint a dramatic foot race!

ML The teams have reached the halfway mark in the 25,000km race to Ushuaia. To reach the next checkpoint, they must choose to travel through either Bolivia or Chile.

PG With three teams already at the checkpoint in Argentina, Dom and Lizzie are over 24 hours behind and must use their ingenuity to claw their way back into the race.
