The Greenville Spinners Bicycle Club has a long history of hosting group rides from the South Carolina Technology and Aviation Center (SCTAC), formerly called Donaldson Center, an Army Airbase during WWII.  The club leases the property from SCTAC and provides porta-potties trash cans, and a picnic table  as a convenience for our members to meet up, park, ride and congregate.

Parking Lot Address: 642 Perimeter Road Greenville 29605
Tuesday Night Rides – 6:00 p.m. Start

The club currently hosts group rides beginning the first Tuesday in April. The rides occur weekly during spring and summer months, ending in mid-September when daylight starts dwindling. The kickoff rides for the 2023 season will start at 6:00 p.m. on Tuesday, April 4 (weather permitting).

A & B group race-pace rides start near the Spinners’ paved parking area and ride clockwise around Perimeter Road, escorted by a Greenville County Sheriff’s deputy. A & B group participants are asked to donate $5 to reimburse the costs of the police, porta-potties and the lease on the property.

The C-Country Loop rides, which vary in distance and pace, will start from the “Club Loop” Drive area.  These rides are led by ride leader volunteers to help maintain the posted pace and ensure safety for all riders. There is no fee to participate in the C-Country Loop rides.

We highly encourage all riders to be Spinners Members in good standing. Membership benefits include discounts at local bike shops, free admission to official club rides and time trials, and supplemental insurance on all official Spinners’ rides. It also helps pay for the club lease on the property and year-round porta potty rentals. See the membership page for more information on these and other additional benefits.

A & B pace/Perimeter Road lap rides gather here:

The classic 31-mile loop riding south through smooth country roads and low traffic neighborhoods.


This 22-mile route follows a similar route to the Green loop but with less elevation


This 20-mile route has even less elevation and is a great ride for beginners or those who desire a more casual, social ride pace.

Note: Groups are requested to take a right-hand turn (counter-clockwise) as they return Perimeter Road to avoid the peloton of A & B loop riders riding clockwise.
