I've just read about the Morris Island Lighthouse again, and I realized that my first race was the "Save the Light" 5K in 2009. I went back and read my race report. I ran the race in 22:03, about which I was satisfied, and I wrote: "One day, I may be able to run a sub-20 5K." Isn't that funny that running sub-20 is now very easy for me, and I'm working on sub-18? Even though I'm more than 5 years older.
