This is a beginner friendly workout inspired by parkrun
(https://www.parkrun.us/) and may become a registered parkrun someday. The course is in Kenneth Hahn State Recreation Area. The 5K distance consists of two laps around the "Bowl Loop" followed by an out to the Stocker St. park entrance and back to the parking lot. It's mostly flat with a few small hills. Run whatever pace you want and meet up at the finish. Additional workout options include tougher hill repeats, and/or 0.8 mile bowl loop intervals.

Start Line -- at the white gate on the loop path where the dirt becomes asphalt, just north of the parking lots.
