I ran the Taylorsville Days 5k on Saturday. I managed to go all race without back pain. I also managed to get a time similar to my time I the last race I ran. It was a pretty decent course, a bit on the flat side, but pretty close to exactly 5k. It also covered a lot of familiar terrain this year unlike previous years.
My Garmin said my time was 27:47, my official race result was 27:46. I love chip-timed races. No worrying about the lineup afterward, or tearing the perforated bib.
