What is your Helix Sport?

I saw this interesting discussion on Jules facebook status:

a unique personal project like seatless unicycle riding over trackless wilderness, a sport that avoids rails, rules, and programmed confinement. The familiar versions of this are cross-country skiing, sailing, hang-gliding, skateboarding, surfing, solitary mountain climbing, thousand-mile walks, things like that. … In a helix sport the players search for a new relationship with themselves. They endure pain and risk to achieve this goal. Helix sports are free of expert micromanagement. Experts can’t help you much in that moment of truth when a mistake might leave you dead. Helix sports are a revolt against predestination.
