Notes
Started watch again after second 8 miles as to not lose data in case of failure. Decided not to stop watch on any walk breaks so mile 18 is long because we walked up giant hill. This portion is pretty hilly and I felt pretty awful after 16, now I know to carry gatorade or gels on anything longer than 16. Very glad to get back to the cars at 19 where I had gatorade and went out to the footbridge and back to make it a full 20. Successful day in that I was on my feet for almost 4 hours but obviously not happy with performance. Will know better next time.
