In the high-stakes game of big-wall climbing, the Shark’s Fin on Mount Meru may be the ultimate prize. Sitting at the headwaters of the sacred Ganges River in Northern India, the Shark’s Fin has seen more failed attempts by elite climbing teams over the past 30 years than any other ascent in the Himalayas. To undertake Meru, says Jon Krakauer, the bestselling author of Into Thin Air, "You can’t just be a good ice climber. You can’t just be good at altitude. You can’t just be a good rock climber. It’s defeated so many good climbers and maybe will defeat everybody for all time. Meru isn’t Everest. On Everest you can hire Sherpas to take most of the risks. This is a whole different kind of climbing."

In January, 2015, American rock climbers Tommy Caldwell and Kevin Jorgeson captivated the world with their effort to climb the Dawn Wall, a seemingly impossible 3,000 foot rock face in Yosemite National Park, California. The pair lived on the sheer vertical cliff for weeks, igniting a frenzy of global media attention. But for Tommy Caldwell, the Dawn Wall was much more than just a climb. It was the culmination of a lifetime defined by overcoming obstacles. At the age of 22, the climbing prodigy was taken hostage by rebels in Kyrgyzstan. Shortly after, he lost his index finger in an accident, but resolved to come back stronger.
When his marriage fell apart, he escaped the pain by fixating on the extraordinary goal of free climbing the Dawn Wall. Blurring the line between dedication and obsession, Caldwell and his partner Jorgeson spend six years meticulously plotting and practicing their route.

We're out to name and shame the most rubbish car from a manufacturer which, frankly, should have known better. And we have a special, surprise fate in store for the car we pick as our biggest loser. In this Top Gear special episode, Jeremy Clarkson and James May try to look for the worst car of all time and the criteria was that the car had to be 'terrible, but not cheap' and made by 'a manufacturer that should have known better'.
