For altogether different reasons, I run very little these days. That's why I went to crossfit. There is some running in the routines and, if I could run, I would follow them. Even without me doing any running in crossfit, my run times have still improved. I could not imagine how good they would be with me doing the running workouts, too!
Back when I was running, I did almost all trail running. I equate trail running v. running on the roads to be about the same as free weight lifting v. nautilus. There is so much more stabilizing going on... that, and I have the attention span of a puppy when it comes to running. I have always been a fan of mixing the running up with biking or some other cardio. Without doing that, you will really feel it (and see it in your times).
With that said, crossfit does seem to do a good job at shocking your body. I can't seem to do any activities that really make me sore. Without regular mountain biking, I have done some hardcore trail riding without getting the least bit sore. Without running in the last 7 months (or really going out there, trying to kill myself), I did my most recent fit test run (1.5 mile) in less than 9:45... which I consider respectable. Keep in mind that I am a 210 lb 36 year old.
