The Dirty South Trail Races take place Sunday, December 7, 2025, at Mead's Quarry near Ijams Nature Center in Knoxville, TN. The event includes the following distances:
- Half Marathon

- Kids Trail Mile
Registration fees vary by date: the half marathon and 10K range from about $40 to $60 depending on when a runner registers. Student entry for those 14 and younger is available for $15 for the half or 10K. A small discount is offered to Knoxville Track Club members. Kids Mile registration is listed around $7 to $9. Registration terms state no refunds and no bib transfers. A special tech shirt will be ordered in late November; registrants after that order date may receive shirts only while supplies last.
Course, rules and logistics
The half marathon course covers about 13.1 miles through the Forks of the River Wildlife Area, William Hastie Park, Marie Myers Park, Ross Marble Quarry, Ijams Nature Center, and other parts of the South Knoxville Urban Wilderness. Trails include rocky, technical single track and smoother mountain bike trail. The half marathon has a four-hour time limit.
Race rules: no headsets, bicycles, strollers, roller blades or pets on course. Aid and water stations will be provided with very small cups; runners are urged to carry personal water. Runners under 12 must be accompanied by an adult to enter adult races. An 18:00/mile minimum pace will be enforced with a course sweeper. Visible lightning within 30 minutes of the planned start triggers postponement procedures; race personnel may delay, alter, or cancel the event for inclement weather. Results are posted on the Knoxville Track Club site and Runsignup. Visit the organization's website for the most recent information.
