Runners - New Runner Needs Advice

[surgtech1956]

Just finished the C25K today. But am I slow, 15 min miles. Whats the best way to improve my speed? I appreciate any advice/feedback. Thank you

Is this "lung" speed or "leg" speed, if that makes sense? Though it can be hard to tell as a beginning runner...

I think its a little of both, probably more lung.

I'm finding lung speed harder to improve, though, like on a bike, it seems to be improving by suffering through intervals/speedwork, hills, and just pushing when my mind says no. Really learning to relax can help - occasionally while you're running, shrug your shoulders up to your ears and then let them flop. And if someone can watch you, have them see if you're leaning forward or sticking your chest out - slight problems with posture tend to be greatly exaggerated while running (when I get tired, I slouch really badly and then - tada! - can't breathe).

For legs - and maybe partly for lungs - most beginner runners overstride, which seems like it would be efficient (larger steps, right?) but uses lots more energy. The correct stride, as I've heard it described, should never allow you to see your feet, since they should be landing directly beneath your knee. If they're in front of the knee, you temporarily stop and then re-start forward momentum with every stride. Tweaking stride efficiency has helped me immensely in the last year but I'm still struggling mightily when my lungs can't keep up.

Edit - one more thing: turnover/cadence. Theoretically, we're most efficient at about 180 steps per minute, though it can vary person to person. A side effect of overstriding (or learning to run while overstriding) is a slower leg turnover, which also essentially means you're hitting the brakes every step. So think shorter, quicker steps. Your legs might take awhile to get used to that but it will eventually make it easier to go faster.

I think if you can run comfortably at 15mm, your form is likely to be very good. The trick is not changing your form when you gain speed. Like anything else, try running intervals, fewer and shorter than what you think you can. Lean forward a little farther at the ankle - NOT at the waist. Open your stride up a little longer behind you - NOT in front. You should feel it in your obliques.

Didn't you say you used to run track when you were younger? I'm betting you find it again sooner than later.

Thanks everyone for all the advice. I ran back in the 80's(about 50 mpw) - just ran for fitness and fun. This is what I was going to try. Since I can run 32 minutes, a couple of times a week, run a shorter distance/time(maybe something like 20-25 mins) and 2 days run the 32 mins, then 1 day increase to 35 mins, then increase the next week so my 32 mins run would be 35 mins and then gradually increase my time/distance. What do you think about this plan?
