The Post Oak Trail Run Marathon is a combination of less than a mile of existing gravel roads, old farm roads, a couple of chat trails, and miles and miles of single track trail winding through meadows and deep woods.
It is a beautiful course with a little bit of everything. There are rocky areas, creek crossings, and a good chance of mud on the trail,and lots of hills.
