The narrow, twisting 12.5-mile, two-lane road that makes up the Pikes Peak International Hill Climb comprises no fewer than 156 turns, climbing to a finish line some 14,115-feet above sea level. The so-called Race to the Clouds has been an essential part of North American motorsport tradition for almost a century, with Porsche a pivotal player for many decades.

Sunday’s 98th staging of this infamous high-altitude hill climb proved especially engaging for Porsche fans, with three heavyweights from the current stable of Weissach thoroughbreds going head to head in the factory standard ‘Time Attack 1’ class.

The headline act for many was the 935 belonging to Bob Ingram and driven by Jeff Zwart, a multiple class winner at Pikes Peak making his 17th start last weekend. Alongside him were two 911 GT2 RS Clubsport cars, which share the same twin-turbocharged flat-six powertrain as the 935, mated to a bespoke eight-speed PDK transmission.
