Two hard runs in a row and heat makes a difference. When I started my run up the canyon, it was 54 degrees. When I finished, it was 80 degrees. That's up by 26 degrees during the 1:46:19 that it took me to run 12.08 miles, which averages 8:48/mile. I drank twice on the trip, but I still lost 3.5 pounds of fluid and am still in recovery mode from the run. |
