I ran 5 loops of the Rivanna Trail and set the first (and hence fastest) known times for 3, 4, and 5 loops of the Rivanna Trail. All loops were in the CCW direction.
The total times from the start were (HH:MM:SS):
3 Loop Elapsed Time: 12:42:39
4 Loop Elapsed Time: 18:17:08
5 Loop Elapsed Time: 23:59:11
It went fine with no issues. My GPS watch data appears to be off a little for the 2nd of the 5 loops, but the total loop times in the GPX file agree with the times we recorded on a tracking sheet. See photos for signed tracking sheet.
My daughter Mary Kwiatkowski ran with me the first 7 miles of the first loop, and the last 7 miles of the 5th loop.
My wife Lisa Kwiatkowski ran with me the last 7 miles of the 3rd loop.
My friend Sean Stanford ran with me the complete 4th loop.
My friend Patrick Paczkowski ran with me the last 4 miles of the 4th loop and the complete 5th loop.
I had 2 aid stations: One at the start/finish of each loop in the back of my car at the Meadowcreek Disc Golf Course. The other one was at approximately 10.5 miles from the start on the trail near the Charlottesville Park and Ride off Avon Street. I used the aid stations to refill food, water, headlamp batteries and a portable GPX watch battery. I ran with a running vest to carry my supplies.
