Didn't Have Much Time So Ran/Walked for 35 minutes

My wife and I went to the 100th South entrance and ran and walked south. We were limited for time and I only ran for 35 minutes. Also, I pushed myself more than I should have, and I was happy to reduce the length of the run. This was supposed to be a rest run, and I shouldn't have pushed myself. However, I wanted to catch up with my wife (she leaves while I'm waiting for my GPS to locate satellites), and I pushed for more speed. My distance today was 1.9 miles.
