Oliva Why would anyone want to run on cement? most of them have nature trails or hiking/jogging trails and such to run on. [log in to unmask] My point is this, these runners are outside in fresh air, doing a circuit training. They're not running as we do. There are numerous people out running on the street with the traffic and air pollutants or on a treadmill in the gym. Most don't have nature trails on which to run, no rivers to cross, or hills/mountains to scramble up. We'll agree to disagree. Oliva
