This route is believed to be the first circle bypass route in the U.S.  Finished in 1958 the Ross Clark Circle, (state route 210) is officially 13.77 miles around the city of Dothan, AL.  Various parts of the circle is ran by local runners with few ever running the complete circle.  However there is an annual 1/2 marathon in October that allow runners to use most of the circle during the race but still falls short of completing it by approx .67 miles.  I believe runners will be looking forward to speeding around the route of "Dothan Circle City" in pursuit of an FKT.

City of Calcedonia Trail

The Fenda da Calcedonia, is the biggest crack in Portugal

If you are a runner and live in the western suburbs of Chicago near the Prairie Path, Fox River Trail, or Great Western Trail, it is likely that you have spent hundreds of hours on the network of trails they form. This route is one large loop and tries to encapsulate some of the best sections of trail. Start at the 0.0 mile marker of the Prairie path in Wheaton, head southwest through Warrenville and wind your way to the Fox River in North Aurora, turn north along the beautiful Fox River Trail and enjoy the river through Batavia, Geneva, St.
