I think I'm going to breakdown and invest in a treadmill - mostly for use in the winter, on bad weather days, or early/late. I'd love to hear recommendations for treadmills considering both quality and cost. I've run 3 marathons, but am also a bigger guy - 6'3", 245 lbs. I worry about investing in a treadmill that doesn't handle my weight coupled with my speed (I'm not fast, but I'm not jogging either). Any suggestions, other than lose 45 lbs?
