I'm not sure where I should be going with my running right now. I used to be content just running 4-5 miles a day, but then I trained for a 10 mile race, and now I'm setting my sights on a half/full marathon. Thing is, I'm also starting an internship in the summer, and I'm in college right now, so I'm pretty sure I'm not going to be able to run a half/full marathon this spring. I'm hoping next spring I'll run the Pittsburgh half/full.
However, I don't know what to do until then. Right now, I'm running 5-6 miles per day, with a long run of around 10 miles once a week. Should I keep lengthening my long runs, or is it not necessary more than a year out? Is it good just to do long runs even when not necessarily training for a race? What else should I be doing? Any good training resources even if I'm not necessarily training for a specific race but want to improve my fitness?
