Set within, Cross Timbers State Park in Toronto, Kansas, the Born To Run primal challenge features a single track forest trail with open meadows, a few small stream crossings, if there has been rain, a couple of slopes, no big hills and a few rocky areas.

In addition, the third weekend in October is traditionally the time of year when all the trees at Cross Timbers State Park are at the peak of their fall colors, so the scenery promises to be memorable
