The XTERRA Tennessee Trail Series moves to Knoxville, TN to bring one of the toughest and most exciting trail runs on the calendar. Only half marathon participants earn series points. The distance options include 13.1 mile or 4.2 mile trail runs. Nestled around a finger of Cherokee Lake, Panther Creek State Park presents a rural playground for mountain bikers and trail runners alike. Winding through the State Park, participants will encounter plenty of rocks, roots, and climbing to test their grit. XTERRA Panther Creek will take participants through the landscape and rugged hills of East Tennessee while exploring this magnificent park.
