The Police Academy uses the Jordan River Parkway as part of the physical conditioning of the cadets. The Academy officials painted a line across the Jordan River Parkway path at 0.75 miles from the Parkway sign in South Jordan. Each cadet had to run to that line and back to the beginning, for a distance of 1.5 miles, within a specified time to complete that part of the cadet training. To me, that line makes a good 0.75 mile marker. Today, I went to that line and back. I mostly walked, but I did a bit of jogging during that workout.
The following picture, taken from the web, shows police cadets training at a local track for their 1.5 mile certification run on the Jordan River Parkway.
