Very scenic course that, as the name indicates, takes runners over four bridges in the beautiful Chattanooga. The course winds through the entire downtown area and various terrains. You run in a park, on public streets, and very briefly, you go down some stairs. When you finished, instead of a cup or disposable bottle of water, participants received reusable water bottles. The race started in the low 40's and warmed to almost 50 when I crossed the finish line. Parking is a nightmare in Chattanooga, and that applied to this race as well. There is also the 7 Bridges Marathon taking place at the same time as this event. My full review is here: http://runninglarge.wordpress.com/2013/10/24/4-bridges-half-marathon-recap-pr/
