With a Saturday date at Colorado National Speedway in Dacono, CO, the NASCAR K&N Pro Series West is back in action for the first time since June 22 at Sonoma, CA. NASCAR Next driver Michael Self has won three of the last four series events, but Derek Thorn – a two-time winner this season – has a slim three-point advantage over Self in the season standings. Cameron Hayley, also a participant in the NASCAR Next program, looks to score his first championship-event victory after starting the season off with a non-points triumph in the inaugural UNOH Battle At The Beach in Daytona. Hayley, who just celebrated his 17th birthday, has scored top-five finishes in five of six K&N West starts this season.

The NASCAR Whelen Modified Tour returns to Monadnock Speedway in Winchester, NH., for a make-up date after rain doused the originally scheduled date on May 11. Defending tour champion Doug Coby collected his first win of the season in the last event on July 13 at New Hampshire Motor Speedway in Loudon. NASCAR Next driver Ryan Preece has a commanding 44-point lead in the standings powered by wins in three of the last four races. The 22-year-old Preece led wire-to-wire a season ago at Monadnock.

The NASCAR Canadian Tire Series presented by Mobil 1, on the heels of its two-race swing through Western Canada, heads to Autodrome St. Eustache (Quebec). It’s the series’ first visit to the .4-mile oval since July 2010.
