I finally made it to the Gainesville-Hawthorne Trail in May 2014. I biked from Hawthorne to Rochelle (8.5 miles). Then I biked from Boulware Springs back towards Rochelle. However due to the steep hills and being out of shape I only did 3 miles. Info has this trail being 15-16 miles long. However the trail goes farther from Boulware Springs heading north towards Jacksonville. That might add 8-9 miles. Also there is no trailhead at the downtown area on SE Depot Avenue. This is a very scenic and mostly rural trail. My full review and lots of photos are on my website.
