10.25 miles in 1:21:50 (7:59 pace) at Alta Ski Area.
While running up the Summer Road and on the uphill trail portions in the Albion Basin campground I paid closer attention to my Garmin that I usually do. On the Summer Road I was averaging about 8:45 pace. On the steeper uphill portions in the campground it was more like 9:25 pace. My heart rate was in the stratosphere so I classified these as threshold pace. That's what uphills at 9000 to 10000 feet will do.
I felt tired and beat up. Took an iron supplement along with my normal multi vitamin and will try to rest some today.
