High Altitude running #2

• I was in Lake Tahoe this week for work and needed to do one run during the 3 days I was there. I decided to do my cross training day at the hotel gym on Monday since I was pretty sore from my long Sunday run. The next day I had some open time in the afternoon so I ventured out to do a short run. The temp wasn't bad in the 70's, but it turns out I was going to be running at 6100 feet. I barely made it 2 miles. I did a lap from my hotel around a small college nearby that had a bark dust trail on the back side. It had a nice hill up to the college where I had to stop both times I went by. 
• After my run I proceeded to have a nice cough for the next hour or so and drank a lot of water. I travel to Rocky Mountain States quite a bit for work so I'm hoping my runs there eventually get easier or at least longer the more I go.
