Featuring a course that unfolds along the rolling hills of the 1,500-acre Robert Allen Park and Retreat Center just outside Monticello, the Allerton Trails Half takes runners along the park’s winding double-track trails along the Sangomon River as well as through its wooded forest areas, gardens and meadows. The out-and-back course for the race will start and finish near Allerton House inside the park.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
