But the continued escalation of slopestyle challenges and gravity of injuries raises the question: Has the sport gone too far?

The bunching together of serious injuries at Crankworx competitions in Colorado and Whistler this year have served to highlight the issue. While the aerial acts continue to amaze and astound, the carnage factor is giving pause.

In Colorado, everybody’s favorite stuntster Cam McCaul took a terrible fall, shorting a front flip and breaking his femur. Cam was his usual gonzo self throughout the episode, telling concerned friends and bystanders that it was simply time to get the thing set so he could start healing and get back on the bike. But a broken femur is serious business, and none of the riders we’ve seen with this injury have come back without a far healthier respect for the damage a crash can do.

Still, Cam can thank his lucky stars he didn’t break a two C-vertebrae like downhiller Dan Atherton, who landed a jump wrong while doing practice runs in his own back yard.

At Whistler Crankworx, leading names fell like flies. Slopestyle competition favorite and hometown hero Brandon Semenuk, fresh off his third straight win at Colorado, suffered neck and collarbone injuries, fellow B.C.-er Darren Berrecloth hurt his arm and wrist on his final 360 and France’s Yannick Granieri had to be hospitalized after landing badly. To show how tough the competition was, Yannick still finished 6th and Semenuk 8th in the overall judging. Go big or go home indeed.

It’s always going to be a tough call as to when a course is just too vertical to be safe. Partly to accommodate more extreme tricks, slopestyle courses always feature variations from year to year, stepping up the drop distances, the berm angles, the jump ramps. There may also be an issue with judging. When the riders who go the biggest get hurt as a result, the ones who get rewarded with the wins are the riders who best manage to balance difficulty with getting to the finish line in one piece. That isn’t necessarily the right way to move the sport forward either.

Ultimately it’s not the public who arbitrates this issue. The public wants the scariest, gnarliest and raddest stunts possible. Instead, it’s the riders who will have to make the call. Sort of like in the Tour de France, when the difficulty factor overrides the fairness of the course and safaety of the cyclists and a rider like Fabian Cancellara or Lance Armstrong says hey, time out — that’s what will have to happen if and when course design and judging philosophy exceeds the bounds of rational wisdom.

We’d be interested in hearing from the riders on this point, as well as their fans. Whether they do it publicly or not, though, there needs to be a conversation about the dynamics of slopestyle with regard to the safety of the sport.

There’s a cross-country tandem cyclist who rides shotgun, letting the stoker sit in front. Why, you ask? Gene Bisbee explains.

Seattle’s Jill Kintner wasn’t the dominating force at this year’s Crankworx that she was last year, but she did take top honors in the Pump Track competition. You have to be super strong to do pump track right. Jill’s progression toward World Cup downhill success continues apace. Check her blog for the full scoop.

Crankworx partial injury rundown: “Brandon Semenuk suffered a neck/collar bone with back flip on last drop. Darren Berrecloth suffered an arm/wrist injury on last jump 360. Yannick went to hospital after a crash on an odd landing.”

Every time Seattle proposes a road diet to reduce speeding cars, traffic congestion, hazardous conditions for cyclists and pedestrians and other ills of contemporary transportation management, a few people get scared.
