replacement therapy

Well if I can't run right now, I'll pick up the cardio slack on the elliptical. 
Same calorie burn in 20 minutes as it did to run/walk 2.5 miles in 30 minutes (tho my mileage is not nearly as far). 

I miss my running but this will work well as replacement therapy. And actually, I found it challenging with all the random level increase and decreases...been using the one at home but looking forward to the new and shiny type that will be at my new gym in mid October!
