I always go farther than I planned

I just don't want to quit running and so I keep taking turns away from the way I planned and away from home. Sometimes if I plan a quick 3 mile it might turn into a 10k or even a 10 miler. Its great to explore some new courses this way. Some of my favorite courses have been found this way and anyway it's not good to keep doing the same courses over and over again every day. Sometimes I just hate to quit running.
