The Bike the Barns cycling tour will feature several interpretive exhibits and farm tours along its route through the Tri-Lakes region later this month.

The fourth-annual event on Sunday, Sept. 29 will begin and end at Tucker Farms in Gabriels. Riders will have a choice of four different routes between 10 to 70 miles long.

Local human rights organization John Brown Lives!, the North Country Underground Railroad Historical Association, the North Star Underground Railroad Museum, the Six Nations Indian Museum and Historic Saranac Lake will each have exhibitions on display for cyclists this year.

“We’re thrilled to dig a bit deeper with this year’s event into some of the fascinating history of the region’s farming communities,” Josh Bakelaar, a program director for the Adirondack North Country Association, said in a statement.

For lunch, cyclists will stop at Sanctuary Farm in Vermontville, land once farmed by John Thomas, a former slave. Don Papson, founding president of the North Country Underground Railroad Historical Association and the North Star Underground Railroad Museum, has researched Thomas and his descendants and will discuss how their story fits into the region’s larger historical context. Riders will also have the opportunity to view a display from JBL called “Dreaming of Timbuctoo,” curated by Amy Godine. Martha Swan, executive director of JBL, will provide interpretation.

Historic Saranac Lake will showcase its cure porch on wheels at the Bike the Barns finish at Tucker Farms. The Six Nations Indian Museum in Onchiota will open its doors for the day to accommodate riders along the three longest bicycle routes. Displays include information about indigenous farming methods and contributions to modern agriculture.
