Every so often you hear someone say: “No big deal, they’re tied to the line.”

Highlining, slacklining above a gorge, isn’t a walk in the park. It’s a big deal. It takes calm nerves and a preternatural sense of balance, but that’s only a start.

Perhaps more than any other sport, highlining takes trust. Trust in the equipment strung across the chasm between life and death, trust in the comrades who tie that equipment tight and trust in your own abilities.

That trust is in full view in the video above, a short piece of high-tension cinema verite filmed by Pierre Chauffour above the Verdon Gorge in south-eastern France. Also on view, is the companionship that comes along with putting it all on the line.

It’s just more proof that good friends make better line companions. After all, they know what it means to keep “tight.” Every Adrenalist needs a team of people to count on.
