The Three Creek Century consists of two ~50 mile loops and two ~25 mile loops which may be combined to create route of 25, 50, 75 or 100 miles. All return you back to the start point at the Penn Twp Fire Company.   There is also the option of the 18 mile ride on the Cumberland Valley Rail Trail (no cue sheets needed)

The 2018 Routes are posted below. Printed cue sheets with more detail will be available at registration the day of the event.

Big Spring Meander (50.8 miles) – This pleasant ride earns its title by following the meandering paths of the Yellow Breeches, Big Spring, and the Conodoguinet Creeks.  It is mostly level riding through rural Cumberland County, but does contain some long gradual hills. The rest stops are at the Cumberland Valley Rail trailhead in Newville and Shippensburg Township Park.  Total elevation gain is 1,809 ft.

If you are riding the entire Century, we recommend that you begin your day with one of the ~50 mile routes.

Opossum Lake Loop (29.8 miles) – This route takes you north and west of Carlisle and features some challenging climbs along with some level riding. A scenic overlook of Opossum Lake is included.  If you are riding the entire Century, we recommend that you ride this route second, after completing one of the ~50 mile options. Total elevation gain is 1101 ft.

Yellow Breeches Ramble (25.1 miles) – This route features enjoyable riding over gentle terrain, although there are some gradual hills along the way.  A portion of the route closely follows the winding path of the world-famous trout fishing stream, the Yellow Breeches Creek. The rest stop is at the midway point at Trine Park in Mount Holly. View scenic farmland highlighted by the large mountain ridges to the south. This memorable route is a wonderful way to complete your 100 mile century ride.  Total elevation gain is 759 ft.  At about mile 23, you can extend this route by seven miles by taking an optional climb up to Kings Gap.  See below.

Optional Kings Gap Climb (7 miles) - The Kings' Gap option is a 3.5 mile gradual climb on a winding tree lined road that leads up to Kings Gap Environmental Center. On a clear day, the view of the Cumberland Valley from the Mansion porch is awesome, but the biggest reward is the exciting 3.5 mile ride back down the hill. Water and restrooms are available at the top of Kings Gap.
