Things to do in Gainesville, FL - Hawthorne Trail
The Hawthorne Trail is my favorite spot for rollerblading and cycling (and walking as well). I like to drive to the La Chua Trail entrance (http://floridahikes.com/paynes-prairie-lachua), but you can also start from near Shands or drive to Boulware Springs.
The trail is about 15 miles each way and offers car-free work-outs (translates to: you do not having to worry about getting hit by a car). You can also stop and walk the La Chua Trail as a side event, and see the Prairie at the Alachua Sink Overlook.
