It just seems crazy if there wasn't an error with the app! My normal pace is around 13 minutes per mile. Tonight it says 6:27 minutes per mile. I did try lengthening my tiny strides a little and I tried some new shoes. I used to be a fairly decent runner....but that was over 20 years ago. I have the active.com iphone app.
And oh yeah......my legs are killing me right now! LOL
I don't know if it's possible but I'd say it seems unlikely. Can't you do the math? Did you run that much further in about 1/2 the time? It just seems to me that if I was running that much faster I would have thought "Wow look how far I went" long before I looked at the app. Hopefully though it's true. I will say that I don't have an iphone but my app has clearly gotten the time wrong in the past.
Make sure you're viewing "average" pace, not "instantaneous" pace, which can be deceptive. Also, be wary when you "try lengthening" your stride. Most people (particularly beginners) do this by reaching in front of themselves with their foot, resulting in overstriding and landing with a straight, extended knee. This can cause a "braking effect" with extra stress on the knee and other parts of the leg. Try to keep the knee flexed and over the ankle when you plant your foot
In reading your post here you mentioned "Most people (particularly beginners) do this by reaching in front of themselves with their foot, resulting in overstriding and landing with a straight, extended knee. This can cause a "braking effect" with extra stress on the knee and other parts of the leg. Try to keep the knee flexed and over the ankle when you plant your foot", I think this may have applied to me as well, not to mention I was doing a bleacher (steps) routine after each routine of the c25k program. You have replied to several of my past posts and I was hoping to get some more info, I'm a brand new runner 53 years old in good health and fairly fit, I began to experience knee pain after d1 w4, but continued with d2 and 3, but am taking today off from completing w5 d1 routine today. I am seeing an Ortho Specialist tomorrow and in the meantime have been icing my knee routinely. Anyway, I'm hoping my knee just needs a little time off and that I will be able to continue running soon. I just want to clarify, when you say "try to keep the knee flexed and over the ankle when you plant your foot" I'm assuming that the proper way for the foot landing is heel to toe? Thanks in advance, hope to be back on track soon!
Well, I would have to say there is no "proper way" to plant your foot. The majority of runners appear to be heel-strikers, that is "heel-to-toe" - studies show around 70% of runners are heel-strikers. There are a lot of proponents for midfoot-striking, (where you land almost flat-footed, with the ball and heel landing almost simultaneously), and forefoot-striking (where the ball lands, then the heel lands lightly). The most recent studies seem to show that there is no real advantage to one over the others (with one exception, see below). Basically, whatever way you plant your feet now, stick with it unless you have a good reason to change (such as repeated injuries). Below is a pretty good video that illustrates good technique. He is running barefoot (which of course you don't have to do) and talks about "natural running" (something that may be a myth) and is basically a midfoot-striker. Watch the position of his knees and legs and where his feet plant relative to his body. Note that his feet are nearly under his body and his knees are flexed and tend to be over or ahead of the ankles. There is a stop-motion at about 1:20, and slow-motion then and later. It's a pretty good video that illustrates basic principles.
The exception: apparently heel-striking while running barefoot can be a problem. Studies show the forces transmitted up the legs in this case are substantially increased. So if you want to run barefoot, you should not heel-strike.
