[https://ridewithgps.com/routes/44182368](https://ridewithgps.com/routes/44182368) 23 miles. Toilets in the beginning, middle and end of the trail. This trail is approximately 23.2 miles with two short but steep inclines and one very shallow water crossing. It took considerable time to design this route, showing the best Reston offers. Our challenge was to cross the Dulles Access Road in an e-bike-friendly way. Most miles are on protected cycling paths, including the W&OD trail. Even if you live in Reston, most connecting trails may be new to you. Just some 30 minutes from Washington DC is Reston. We will be e-biking from the Water Mine Family Swimming Hole to Reston in the vicinity of Reston's man-made lakes. Reston is a recently established urban area. It was founded in 1964 to revolutionize postwar urban planning. It is known for its two golf courses, lakes, ponds, a high density of trees, and open spaces. We will visit the Vernon J. Walker Nature Education Center during lunch. The trail is on asphalt roads and paths with occasional short, but steep inclines and declines. Please bring snacks, lunch and plenty of water. **Free Ride With GPS for E-Bike Lovers** The Ride With GPS E-bike Lovers club membership is now free as www.ebikelovers.com generates sufficient income from ads to cover the costs.

The distance will be 23.2 miles or shorter any time you are fully satisfied with biking for the day. For the E-bike Lovers group to succeed, we must carefully grow our membership. Please feel free to invite other E-bike lovers, spread the word, and let's have fun. As usual, non-assisted bikers are most welcome.

[https://ridewithgps.com/routes/34720279](https://ridewithgps.com/routes/34720279) 23 miles. Toilets in the beginning, middle and the end of the trail. From Sycamore Landing, we e-bike on the C&O towpath to White's Ferry, where the group stops at the Potomac River for a picnic. The ferry has a restaurant known for its pickle burger. From the ferry, we return via River Road in Montgomery county's rustic farmland. The scenery is particularly fine everywhere along this 23-mile round trip. We will be biking in hilly terrain at the end of the trail. Most of the trail is flat. See also: https://ebikelovers.com/2021/01/17/trail-4-maryland-e-biking-from-sycamore-landing-to-whites-ferry/ This event will be a combined towpath and farmland ride to Whites Ferry, originally designed by David Winer, former chair of the Friday biking group. Whites Ferry is out of commission, but this doesn't affect the ride as we will not cross the Potomac. We meet at 10:00 a.m. at Sycamore Landing. We leave at 10:15 AM. See the map above for the ride route and directions to reach the parking lot at Sycamore landing. The Meetup map guides you to the Sycamore Landing parking lot as well. **Nota Bene: By car, the turn from River Road is 16 miles from the I 495 Beltway, and the parking lot is all the way down this dirt road next to the canal towpath.** The scenery is particularly fine everywhere along this 23-mile round trip. The riding surface beside the C&O canal is typically packed clay/gravel except near Whites Ferry, where it has been reworked into a smoother path. The route through the Montgomery Agricultural Preserve is a seldom-traveled road of packed gravel similar to the towpath's surfaces. Lunch: Brown bag at picnic tables overlooking the Jubal Early car ferry. Snacks and sandwiches are available at the adjacent store. The group stops a few times for slower riders to catch up. The distance will be some 22 miles or shorter any time you are fully satisfied with biking for the day. **Please remember to charge your bike, check your tires and brakes, and consider packing an extra tube.** **We recommend downloading the Ride with GPS route map to enhance your independence.** [https://ridewithgps.com/routes/34720279](https://ridewithgps.com/routes/34720279) **Free Ride With GPS for E-Bike Lovers** The Ride With GPS E-bike Lovers club membership is now free as www.ebikelovers.com generates sufficient income from ads to cover the costs.

About the C&O Canal: The Chesapeake and Ohio Canal operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains. The canal’s roots begin with George Washington’s dream of a waterway trade route. 74 locks were built. About White's Ferry: Historic White's Ferry is the last of 100 ferries that used to operate on the Potomac River. This ferry, named after the confederate Civil War General Jubal A. Early, connects Whites Ferry Road in Montgomery County, Maryland with a road by the same name in Loudoun County, Virginia. The cars line up on what looks like a boat ramp and drive down onto the ferry. Once loaded, the ferry follows a wire cable to the other side of the Potomac.

https://ridewithgps.com/routes/54667858 20 miles round trip to Leesburg. Keep going for a longer ride. Numerous toilet facilities along the route. Picnic lunch at Raflo Park or BBQ along the trail. We'll ride on the W&OD (Washington & Old Dominion), a paved multi-use rail-trail. We'll meet at the W&OD parking lot off of Pacific Blvd in Sterling, VA at 10:00am and start out riding west on the trail at 10:15am. See map for location. The ride will be out and back on the same trail. Minimal navigation required. Many E-Bike Lovers stop at 10 miles in Raflo Park in Leesburg and turn around for a 20-mile round trip. Some choose to ride further west on the W&OD before turning back. You can make the ride as long or short as you want, but we'll aim for 20-25 miles with the group. Raflo Park is a comfortable place for a picnic lunch. Or have a quick snack and stop for BBQ at Carolina Brothers BBQ, which is right along the trail, just 3.5 miles from the ride start. They have indoor and outdoor seating and bike racks. (See the picture.) A lock is recommended if you'd like to eat inside. Or get one of your fellow riders to keep an eye on your bike while you order food at the counter. (Note: there's also a brew pub along the trail - Old Ox Brewery - about a mile from the parking lot.) Please bring plenty of water, sunscreen, as well as snacks and lunch if you do not want BBQ. Pump your tires, check your brakes and consider packing spare tire tube. Please respect the right of way of horses and pedestrians while on the trail, and give plenty of warning and space when passing. Our route has minimal elevation and is less congested than many areas on the W&OD. There are few street crossings, and a good amount of shade, so it's a comfortable and relatively easy ride. As always, non-assisted bikers are most welcome. **Consider downloading the Ride with GPS app and the route map from Sterling to Leesburg.** https://ridewithgps.com/routes/54667858 **Free Ride With GPS for E-Bike Lovers** The Ride With GPS E-bike Lovers club membership is now free as www.ebikelovers.com generates sufficient income from ads to cover the costs.
