Notes
At 7300 ft for the first time. The extra 2000 ft from Gardiner to Old Faithful made a big difference! I was feeling the lack of oxygen about half mile into the run. I ran by Old Faithful and a bunch of other geysers on a nice paved path. It'll make a good 5 mile out and back once I add on some to the front end. Mapped it out and got 4.7 miles so pretty surprised with the pace.
Midway through the run I could hear a tourist trailing me so I slowly picked it up so I could drop him but I definitely felt it but my plan succeeded and he was dropped after 20 seconds. Good to know I'm not the only one feeling the altitude!
