Rt. 128/95 to Exit 29, Rt. 2 West. Go 4.6 mi., look for the Rt. 126 sign, and turn right at that intersection onto Walden Street. Bear right at the fork. At 1.2 mi. in Concord Center make a left onto Main St. and a right into the town parking lot. The Visitor Center is at the south end of the parking lot. By commuter rail and bicycle: From the Concord station, head north on Sudbury Road, which merges into Main Street, then take the first left onto Keyes Rd -- about 1 mi.

18 miles on jeep roads and trails around Concord. Mostly off road but crossing many of the main roads into/out of Concord allowing easy bailouts if time or energy run out. Plan on 3 hours for slow riders and 2.5 or less for those with MTb or CX experience. No drops and I'll ride with the slower folks. More techy than a road ride but less intimidating than mountain biking - hence the name "gravel ride". Start at the Keyes St parking lot in Concord Center at 9:00. We should finish before the rains starts. Bring your gravel, CX, or gravel bike. Any questions call or text me at 617-610-1875..
