In terms of the intensity level, it's a far cry from a bowling league.
But when it comes to things like camaraderie, conviviality and competition, the adult rock climbing league at Vertical Endeavors isn't all that different.
"It's really fun to challenge myself," said Rick Brauer of New Brighton after successfully navigating a tricky climb. He had crammed himself into a corner between two 30-foot walls before edging his way to the top.
Back on the ground, Brauer's hands were still caked with white chalk — as opposed to the grease one might find on the fingers of a bowler snacking between frames. He shook his arms out to relax the muscles in his forearms as he surveyed the climbing wall he had conquered, pondering which one to tackle next.
His teammate, Selima Shafi of Minneapolis, kept her eyes on the wall, too, studying the other competitors working their way up. "I learn a lot by watching other people climb," she said.
Rock climbing is gaining popularity in leaps and bounds — or, at least, in chicken-wingings and heel-jammings. In 2012, 6.9 million Americans participated in climbing, up from 5.7 million — a 21 percent jump — the year before.
While the Climbing Wall Association trade group extols the virtues of the sport's total body workout, it hasn't taken rank-and-file climbers long to discover the competitive possibilities. In fact, a movement is afoot to add it to the Olympics, where last year climbing made it on the short list of sports being considered for the 2020 games.
"Gym comps — we call it 'comp' climbing for 'competition' — are becoming very popular," said Michelle Emmel, who oversees the leagues at the Vertical Endeavors facility in Minneapolis.
