Agreed. Stride rate depends on the speed, your inseam, leg weight, shoe weight, and body mechanics.
Well, sure, of course. Different things work for different people.
1) If you're a longer-legged runner, your most efficient running at a given speed is *likely* (not absolutely always--there are other factors involved) to be at a somewhat slower tempo than that of a shorter-legged runner (of roughly the same ability), running at the same speed. That just stands to reason.
2) Doesn't the "magic" number of 180 steps/minute--i.e. precisely three steps/second--seem a little suspicious to you? Doesn't that seem just a little too convenient?
[It reminds me of what they used to say about Gerschler-Reindell's interval training: "get the pulse up to 180, then let it return to 120." Sorry, it just seems unlikely that human physiology would conform so neatly and precisely to an arbitrary division of the planet's daily rotation period...]
Jack Daniels was the guy who perhaps did the most to popularize the 180/minute concept. But I clocked one of his runners in a cross-country race, and she was at 200. Didn't seem to hurt her efficiency--she won Nationals the next week--and whaddaya know, she was a short-legged individual.
3) All that said: it's unusual for anyone to be running at his greatest efficiency if he's below 150 steps/minute, even at 7:00/mile.
I agree with the suggestions about including a bit of faster work throughout the training cycle; in particular, including a few pickups/striders, a couple days a week, can help develop/maintain an efficient tempo at faster speeds. (When doing these 100m accelerations, a distance runner should focus on gradually increasing tempo--turnover--rather than on lengthening the stride.)
But I think the biggest help (for most) in developing an efficient turnover that's *closer* to 180 is developing leg strength--even if that seems nonintuitive. Yes, hills help with this; but doing leg press (or squats) on a couple of nonconsecutive days/week may be more useful for those who don't have good leg strength to begin with:
a) Start with light weights *and proper coaching* to make sure your technique is correct and safe. For one week, just include one set of 10-15 reps per session; then spend two weeks doing two sets/session; then move to three sets. You should be gradually increasing the amount you lift, consistent with maintaining good form.
b) After spending three weeks on sessions with three sets of 10-15 reps, move to doing a single set of 10-15, mostly for warmup, and then two "work" sets of only 3-5 reps. Continue moving up your weights (while *constantly being monitored for proper form*)--you'll find that you can get to a very substantial level of resistance on the low-rep sets.
Do NOT plateau/stagnate at light weights, or focus on doing more reps--the greatest benefit comes from higher intensity, NOT more reps!
c) Ideally, you should do a few of the abovementioned accelerations *after* your leg-strength session. The high-intensity resistance work "wakes up" your legs' neuromuscular motor units; then the pickups teach those units to fire in a smooth, efficient, coordinated sequence.
Because you're using the accelerations to teach yourself a new movement skill, ideally you should do them when fresh. That means complete recovery between repetitions; it also (ideally) means doing them *early* in your training session.
That could mean a few minutes' warmup activity (jog or bike or whatever); then lifting, if you're doing it that day; then the pickups; and THEN the bulk of your training, whether an easy run or track work or whatever.
[Once the new movement pattern has been well learned, you can maintain it by doing strides at the end of easy runs; but while you're still learning to handle a higher tempo with relaxation and efficiency, you should try to do the "learning" work when fresh.]
