This makes it excellent for hill workouts or building leg strength.

The trails are primarily composed of compacted dirt and gravel, though some sections may include larger, looser gravel. Joggers should be mindful of potential obstacles such as erosion, ruts, and scattered natural debris like pine needles, especially after rain.
