What's a better way to improve run time other than just running more?

Well, there is a lot to say about quality vs. quantity. I would combine weekly shorter intense workouts with LSD (long slow distance). More intense workouts include intervals over various distances from 100 yards to 800 meters. Fartlek gives you a chance to get some distance work in with faster repeats to increase the heart rate and work anaerobically. Upper body weights are important as well but focus on less weight and more reps. than bodybuilders. Hills, whether stadium stands or natural terrain really give an intense workout to develop leg muscles and lung capacity. Weekend long slow distance runs build endurance and most importantly increase muscles in the legs. Strong calf and thigh muscles are absolutely imperative to fast distance times. Ok, now other ways to improve times besides running? Swimming is great for developing lung capacity. Basketball is great for stamina. Cycling is great for building leg muscles but not necessarily the exact combo for distance running. Nothing is as good as running but not necessarily more, just more quality. Good Luck!

land on your toes not the whole foot.

Lean to the side as you turn a corner, kick off with your feet so your not on your tiptoes, point your fingers, and if you can, tilt forward a little so the wind passes you easier. Good luck

Getting in shape overall preferably cycling? on a stationary bike and just seriously running more and doing sprints
