Mountain bikers seem to have an unwavering desire to challenge how far they can push their limits. For some, it means jumping farther. For others, it means riding a line that terrifies them. For Whistler legend Adam Billinghurst, it meant attempting to descend one million vertical feet as quickly as possible.

Watch Adam Billinghurst in One Million Down as he takes on one of his life goals of achieving 1 million vertical feet on his bike. “I’ve wanted to ride 1,000,000 vertical feet in the bike park for almost 10 years now. You don’t get to do a million of a lot of things. The things you do, you rarely think about: how many breaths you’ve taken, grains of rice you’ve eaten, said the word ‘and’. It just seemed like a good number.”
