Yesterday I was planning on an 18 mile run. Although I intended to get up and get out on the road early (for a weekend), I slept in a little longer than I planned. I was trying a new water bottle belt that didn't work so well and I had to go back home to get one of our older belts. Then I started out relatively fine, but a little fast. I tried to slow down several times to be at the pace I wanted (around 8:40), but found myself going faster more often than I'd like. I ran the first 5-6 miles on a familiar route, but was trying a new addition to my route to get a 9 mile out to do an out-and-back run. It was hillier than I realized and I had run hills yesterday. About 8.5 miles in, something started to not feel right about the run. I kept at it for a while longer and then stopped my run.
This is only the second time I've stopped a run early in about 8 years of running. I have ended runs outside due to weather, but finished them on my elliptical. This one I didn't finish. Something just didn't feel right. I was disappointed, but didn't feel down. Until about an hour or so later. Since then, I've felt off, wondering if I should have toughed it out or somehow tried to finish. I suspect i could have finished, but maybe I needed to not complete this run to remember how much planning to run is an important as doing the run.
Sorry for the rambling, but I'm still processing the run and the lessons I learned.
