It was good weather: 68 degrees and the sun didn't come up until just as I was finishing. I needed to get to work early, so when I started my run 5 minutes late I knew I had to either cut my run to 3 miles, or do the full 4 miles in 35 minutes or less. I started out slow, but quickly picked up my speed and chose to see how fast I could do my 4 miles. I hadn't run far or hard in a while, so my legs felt rested and energetic as I gradually increased my speed with each mile. I started to tire around the 2.5-3 mile mark, but still pushed myself to a 7:40 final mile split and the fastest mile of my run. Felt good to push myself to one of my fastest 4 mile times in quite a while. Also feels nice to think that I could've pushed myself harder and that I have more potential left in me for the near future. Thinking that after my next half I might spend more time working on speed instead of endurance.
