So if I can do the elliptical at a moderate pace (probably a little quicker than a jog if I was on a treadmill) for 60 minutes without getting too winded how many miles do you think that would be if I was to run it on a treadmill? I know that this could vary greatly, but I'm just looking for guesses.
From my own personal experience I can tell you resistance level between 5 and 8 doing approximately 140 to 155 strides per minute nets me about 2.25 miles in 28 minutes... Not sure if this will help you or not but it would kind of give you something to compare it against maybe... Hope it helps
Best thing would be to use HR zones so you can get a comparable effort level. You might also consider keeping your cadence at around 90 left footstrikes per minute for an experience more like a run... although on some ellipticals this can be a little hard. You'll still have to transition back to running slowly because the elliptical doesn't really give you the impact that running does - so your muscles won't be used to it any longer.
Personally I just dress in layers and head outside for the most part.
I think the problem is that, although they seem similar, it's a different kind of experience and it's not really appropriate to compare them. I mean, the elliptical has none of the impact that running does, so no matter how far you go, you aren't keeping up the muscles in your legs that protect the joints from the constant impact. So if your main goal is to keep up your distance running endurance, well, you are going to have to continue to run. Think of it instead as a way to keep your VO2 level (oxygen absorption and cardiovascular level) up.
I enjoy the elliptical as a change of pace, but I never count it as even close to a treadmill run. Generally I think of 10 minutes = 1 mile, but never more.
First you need to know the stride length of your elliptical. I use one that has adjustable stride, 12, 15, or 18 inches. I usually set mine on the 18 inches but the other lengths emphasis slightly different muscle areas. Once you know the stride length, there's a chart you can follow at www.walk4life.com/customerservice
that will convert steps taken to miles based on your stride length. my 18 inch stride takes 3158 steps to make a mile. The website has a calculater that will compute this for you, just input your steps and your stride length and there you have it.
