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 Oxford Odyssey 200K begins and ends at the Chamounix Carriage House in Philadelphia. True to its name, the route is a journey through the varied landscapes of southeastern Pennsylvania, from the quiet neighborhoods of the Main Line and the Great Valley to the Brandywine Valley, horse country, the historic town of Oxford, and the wooded valleys of northern Delaware.
Departing Chamounix, the route quickly leaves the city behind, weaving through the quiet neighborhoods of the Main Line before descending into the Great Valley. Here you'll join the Chester Valley Trail (CVT), an increasingly popular multi-use trail that provides a peaceful, traffic-free ride through Chester County. The trail carries riders past Exton before returning to the road near Downingtown.
From Downingtown, the character of the ride changes as the route enters the Brandywine Valley. Quiet country roads follow portions of the Brandywine and Doe Run Creeks through one of Pennsylvania's most scenic cycling regions. Rolling terrain, historic stone buildings, and picturesque horse farms make this stretch a favorite among local cyclists.
After passing through Cochranville for the first control, the route follows the peaceful Muddy Run valley toward Oxford, a town with deep agricultural roots and home to Lincoln University, the nation's first degree-granting Historically Black College and University (HBCU).
Leaving Oxford, riders head southeast toward the wooded valley of White Clay Creek before briefly crossing into Delaware for a control in Hockessin. From there, the route begins its return to Philadelphia, traveling through Delaware County on a mix of quiet suburban roads before reaching the familiar streets of the city and the finish back at Chamounix.
