Route Approval
This route is pending RUSA approval. While we do not anticipate significant changes, please check the event webpage before the ride for the latest route, GPS files, and cue sheets.
Not Sure Which Distance to Ride?
We are offering a 200K, 300K, and 400K on September 19, and the registration fee is the same for all three events. If you're deciding between distances, we recommend registering for the longer event. Riders may switch to a shorter distance at any time before the start, giving you the flexibility to make your final decision based on your training, fitness, or the weather.

Chamounix, also known as Montpelier, is a historic home located in Fairmount Park, Philadelphia, Pennsylvania. The Federal-style house was built in 1802 by George Plumsted who was a wealthy Philadelphia merchant, then enlarged to nearly double its original size by subsequent owners after 1853.
We will use the Carriage House for our start, finish, registration, and lodging. The Carriage House is the building on the left before the eyelet loop at the end of Chamounix Drive. Do not confuse the Carriage House with the Mansion, which is partway around the loop on the right.
In our opinion, the safest place to park is the the Hilton/Homewood lot just off of city avenue. Here is a Google map link. Price is $13/day. As far as we know, this fenced-in lot is secure and it's a very short, easy bike ride from this parking area to Chamounix. There are free on-street parking alternatives a short distance away, including along W Ford Rd, that may be reasonably secure because of the residences and businesses nearby.

We believe that immediately outside Chamounix is not a safe place to park, as there have been instances of petty theft in the area. Should you decide to park near Chamounix anyway, do not leave valuables in your car. There should be nothing visible that might tempt thieves. If you must leave clothes and minor gear someplace during the event, it would be best to leave these inside the Carriage House, but please don't leave anything of great value. For Carriage House events, please park cars along Chamounix Drive in front of the Carriage House as shown in this diagram. Do not park back in the circle by the mansion or on the side alley to the left of the Carriage house. Park on the left side of Chamounix drive within easy view of the front porch of the Carriage house. Park end-in, not parallel to the curb.
Suggested parking locations for the start/finish are public places, with theft and vandalism a real possibility, especially in cities. Park during the event at your own risk. Please do not leave valuables in your car during the ride.
Riders are advised to make sleeping arrangements at or near the start/finish. Please don't try to drive a long distance before or after a tough brevet. Multiple options are available.
As you approach the finish control there are two buildings in the cul-de-sac eyelet. We are in the Carriage House on the left awaiting you with refreshments and eager to hear your tall tales, some of which might even be true.
This event needs volunteers for the following jobs:

The Lancaster Loop 300K begins and ends at the Chamounix Carriage House in Philadelphia. Following the same scenic opening as the Oxford Odyssey 200K, the route travels through the Main Line, the Great Valley, and the Brandywine Valley before reaching Cochranville. From there, the journey continues west into the heart of Lancaster County, showcasing the rolling farmland, quiet back roads, and small towns that have long made this region a favorite among cyclists.
Departing Chamounix, the route quickly leaves the city behind, weaving through the quiet neighborhoods of the Main Line before descending into the Great Valley. Riders join the Chester Valley Trail for a peaceful, traffic-free stretch through Chester County before returning to the road near Downingtown. From there, quiet country roads follow portions of the Brandywine and Doe Run Creeks through one of Pennsylvania's most scenic cycling regions, passing historic stone buildings and picturesque horse farms on the way to the first control in Cochranville.
Rather than turning south toward Oxford, the route continues west into Lancaster County. Riders visit controls in Quarryville, Ronks, and Lititz while passing through the fertile farmland and picturesque villages of Pennsylvania Dutch Country. The route also includes the Lititz–Ephrata Rail Trail, offering a welcome break from the road before returning to the countryside.
Leaving Lancaster County, the route enters the forests of the Hopewell Big Woods, one of the largest remaining expanses of unbroken woodland in southeastern Pennsylvania. After winding through this rugged landscape, riders descend into the Schuylkill River Valley and follow the river east toward Philadelphia. The Schuylkill River Trail provides a fitting finale before one last climb returns riders to the finish at Chamounix.
