As a result, our staff creates what they would want to experience themselves; a reflection of their dedication to trails and their love for the outdoors.

Singletrack Trails was Greg’s gateway to becoming a serial entrepreneur. Since 2004, Greg has significantly impacted six different ventures. Through that time, he has focused to grow Singletrack Trails’ revenues, onboard key staff members, and continue to generate a great product on the ground. Challenging the glass ceiling that the trails industry has commonly accepted, Greg finally shifted his focus with the company as an owner-operator to the Chief Encouragement Officer in 2016. Through that time, revenues have doubled, staff size has doubled, a full-time business development staff has been added, and additional revenue streams have been created. Greg has shifted Singletrack Trails from a boutique trail construction company to a multi-faceted outdoor recreation development firm.

James Flatten joined the Singletrack Trails crew in 2007.  As the Chief Trail Supervisor, he is now responsible for ensuring that projects are completed on time and exceed expectations.  His career as a dirt shaper was packed into prominence as the Lead Course Designer and Chief Builder for the Ranchstyle Mountain Bike Festival near Grand Junction, Colorado. Knowing how to build competition courses for the 1% of mountain bikers, as well as extrapolating that knowledge to build dirt jumps, pump tracks, and rhythm trails for the 95%, is James’ specialty.  He has been adding the “free” to freeride trails since 2002. With James on the project and in charge of dirt shaping, everyone will be happy.
