Trying to improve my running

This run felt surprisingly good, given that I only slept for 2 hours since Friday morning(with 2 runs in the interim) prior to this run on Saturday afternoon. I really wanted to run up Wasson peak to get some vertical as well as some trail work. The first mile of this run is a gradual up hill. I felt like it was nothing. The next mile is mostly made up of semi-steep switchbacks. most times I have needed to walk at least 1/4 of this portion. today I was able to run the whole thing with only a short rest at the saddle. I then was able to run most of the rest including over half of the steep switchbacks at the end to get to the summit. It was so much more than I have been able to do prior to this. I then tried to push the downhill as much as i could to strengthen the quads for the speedgoat. I felt like the whole trip was the easiest trip up to the summit I have had. Comparing this to my prior runs up the mountain after it was over it turns out it was my fastest run by 20 seconds however since this was a little longer run it turned out to be 13 sec/mile faster. It was a lot faster than my most recent runs here.
