Ironman Kona 2017: New bike course record for Cameron Wurf

The australian and his Bolide TT did it! 4:12:54 over 112 miles (180.25km) for an average speed of 26.68mph (42.764kph), more than five minutes faster than the previous record.

In his first Ironman world championship as a professional, former WorldTour racer Cameron Wurf was fastest among several triathletes to break the existing bike course record Saturday in Hawaii. It was Wurf’s sixth Ironman event of 2017, and the second time he’d raced the Ironman world championship in Kona.
