World's Toughest Trucker

The eight truckers meet for the first time in Cape York, one of Australia's most remote regions and find out they'll be working in pairs. They learn that they'll be hauling wild cattle south, over three days, to greener pastures and it's vital that they get them there safely.

Starting from Alice Springs, the eight truckers' ultimate Australian challenge is to haul four huge, prefabricated buildings for a medical center across 500 miles of hostile desert to the remote Aborigine community of Kiwirrkurra. Driving with the same partner as the previous challenge, at the end of this three day journey, the weakest team will leave the competition.

After the Australian eliminations, the six remaining truckers take on the infamous BR163 road through Brazil's wild and unruly cattle lands. Their cargo is 11 x half ton concrete pipes. This load is oversized, fragile and near impossible to secure — as they soon discover. In new driver pairings for the first time, their 3 day 360 mile journey becomes a battle between speed and strategy with surprising results.

It's half way through the competition and this job is the game changer. Six truckers travel deeper into the Amazon to deliver fishing boats to a fishing community along brutal and unforgiving, dirt tracks, fueled by adrenaline and competitive spirit two of the teams race aggressively through the jungle for a winning time. Meanwhile, the third team take a steadier approach. Which strategy will deliver the best results?

The remaining truckers left in the running are split into new pairs as they take part in a three-day challenge of collecting 60 ton loads of timber from 3,000 feet up a Canadian mountainside and taking them back down the valley.

The remaining truckers left in the competition are in Mongolia. They find it hard to deal with the remote and hostile environment and battle with their old Russian trucks.

The remaining truckers left in the competition are thrown out of their comfort zone after they travel to India. At the end of the show there is another elimination.
