There is a moment on a steep descent when the whole world gets very small.

Mine came on a rocky, rutted ribbon of single track near Vernon, British Columbia. The trail dropped away at 35 to 40 degrees. A large fir stood on the inside of the line. Between my handlebar and its bark, there was less than two inches of air.

I was on a 450 lb adventure bike. If I touched that tree, the tree would win.

I will admit I was afraid. But I have rarely felt more alive.

The Adventure Bike Gathering is a different kind of rally. There is very little organization and no pampering. Riders show up in Vernon, talk over breakfast and sort out their days together.

ADV Pulse once noted that the organizers especially love seeing big adventure bikes, and riders working together to get those bikes through challenging trails. They also warned that some rides are very challenging and all of them carry real risk.

They meant it. This was some of the most challenging riding I have ever done. Loose rock. Deep ruts. Trees so tight you choose a line by the width of your handlebars. Descents so steep the front wheel feels like it wants to go first and leave the rest of you behind.

A 450 lb bike does not forgive much on ground like that. You cannot muscle it. You stand, stay loose, look where you want to go and trust the bike to do what it was built to do.

So why do it? Why point a heavy bike down a hill that scares me?

Mark Twain once wrote, "Courage is resistance to fear, mastery of fear, not absence of fear." I think he was right.

Researchers have been asking the same question. In a 2013 study in the Journal of Health Psychology, Eric Brymer and Robert Schweitzer interviewed 15 people who take part in extreme sports. They described fear as a real, physical feeling. They learned to manage it, and many came through it changed, more ready for the hard things of everyday life. The British Psychological Society summary quotes one participant calling fear a healthy emotion that "keeps you alive."

There is another piece to it. Psychologist Mihaly Csikszentmihalyi described a state he called flow, total absorption in what you are doing. It tends to show up when the challenge in front of you matches your skill, in the space between anxiety and boredom. Researchers have linked motorcycle riding and motorcycle travel to that state.

There is a fair caution here too. Falko Rheinberg interviewed 41 motorcyclists and found that the deeper riders went into flow, the riskier they rode. A later study of flow and risk found the same pull in kayakers and climbers, mostly among beginners. Experience seemed to protect. Feeling alive is a gift. It still calls for good judgement.

Something else happens on a descent like that. I feel small.

The mountain was here long before me. That fir was likely standing before I was born. Eric Brymer and Lindsay Oades found that people in extreme sports often come away humbled, aware that nature is far greater and more powerful than we are. As Scienceline reported, real danger puts the fragility of your own life into perspective.

I think that is where faith quietly comes in.

Those words do not ask for the fear to go away. They trust that you are not alone in it.

On that descent near Vernon, I was still afraid. But I was not afraid alone. Fear on one side. Trust on the other. And somewhere between them, the clear sense of being alive, and of being held.

Your hill may look different from mine. It might be your first gravel road, your first river crossing or your first night camping off the bike. The size of the hill matters less than the step you take toward it.

Find your edge. Respect it. Bring good people with you. Then lean into the fear a little at a time and see what it teaches you.

Helen Keller put it simply: "Life is either a daring adventure, or nothing."

Ride safe.
