100 Central FL bike trails
take a browse at this link ...
{edit] Since I've been mostly a lurker here, I'm not yet allowed to post a link to another site. Do a search for 100Floridatrails dot com --> Trails --> Central Florida Region. There you will find detailed maps of a number of decent trails in the area.
I'm in Lakeland. Not too far from Lake Wales. You'll find a decent amount of paved trails in Polk County. The development of the road infrastructure here did not anticipate bike lanes. I no longer ride on the roads here.
