I want to try and follow my running training schedule as closely as possible with the elliptical trainer (the only thing that doesn't aggravate the injury), while I wait for an injury to heal. How do you convert distance on the elliptical to distance on the treadmill? For example, if the elipitical says I went 8 miles, is this the equivalent to running 8 miles? Also, what is the ideal height/resistance level/strides per minute? Any other suggestions? Thank you!
