I had a very pleasant run up and down Snow Canyon. The first 6 miles are slightly uphill with a few steeper sections. I ran the first 10 miles at an 8:00 pace and then picked it up for the last 2 miles at a 6:48 pace. These miles had a small negative grade. I wanted to run them at a 7:15 pace, but since they were aided I was able to go a little faster.
