Proceeds from the Brier Creek Trail-A-Thon will help build the final phase of the trail system, known as Phase 4.  This phase of construction will provide a trail connection that travels below the waterfall and then out toward the point loop.  This creates a quicker trip out and back to the point loop and allows folks to spend more time riding, running, and hiking close to the water.  This will ultimately make Brier Creek Trail safer for all users, allow for more beginner cyclists to use the trail, and better facilitate race events.  This trail work has been designed and flagged by a professional trail builder.  The fundraising goal for this project is $15,000.

There is a base fee of $35 for participation (excluding the kids run).  For each additional event you participate in, there is a $10 fee.  The Kids Fun Run is $15.

Brier Creek Trail was built and is maintained through a partnership between The Southwest Kentucky Mountain Bike Association, Nolin Lake State Park, Friends of Nolin Lake, and the US Army Corps of Engineers.  Throughout the years, businesses and individuals have contributed of their time and finances to sustain this effort.  This event is a fundraiser to improve Brier Creek Trail. 

We encourage you to donate to support this work.  Brier Creek Trail is a world-class facility with regional visibility.  More information on the trail can be found here:  More information about the Friends of Nolin Lake can be found at
