This bicycle ride is in support of events leading up to “Sun Day”, with an optional discussion of Solar Energy at a local pub following the ride. “Sun Day” is a day of action on September 21, 2025, celebrating the power of clean energy, sponsored by a coalition of grassroots organizations, such as Third Act PA, and many others.

This is a nice ride for beginners and those who don't ride often.

The ride will be limited to 15 participants.

Looking for a longer route? There is also a 22-mile version of the ride, ending at the same time. See the 9:30 a.m. Sun Day Delaware River Towpath 22-mile Bicycle Ride to register.
