I didn't know memorial park had a paved path?
Or you can come up to Highway 6 and Clay road. There is a 8 mile roundtrip ride that you can start out in a nice park.
Or you can go to Terry Hershey park that has a path that goes from highway 6 to the beltway and is about 15 miles roundtrip. Depending on the hour there are many other people - walkers, joggers, etc. but it's a very fun ride if you're not looking to get a hard workout.
