A couple months ago I started running again, and to keep myself motivated I've decided to sign up for a 5k this spring. Obviously that's not too difficult to run, but I'm wondering what the best way is to improve my time? Right now I'm normally running indoors on a treadmill because it's cold outside, and I don't really like running and appreciate having a TV to distract me. Sometimes I do non-impact cardio instead (generally on an elliptical machine) because I broke my ankle this summer and it still gets rather sore if I run on it too much. If I want to lower my 3 mile/5 kilometer time am I best off just running that distance and trying to regularly up the pace, or is there some other training approach that would work better?
