Heading Up Pikes Peak

Have a time slot starting at noon. Should be interesting given we live at almost sea level. I was at Ft Carson on TDY back in 86. When we checked in to our motel we decided to take a little run. I didn’t make it 1/8 mile before I ran out of air. Kicked My arse. We were told later it take one to two weeks to acclimate to the altitude.
