Ok, so, just downloaded app.....arghhhh. I'm an almost 46 yr old who hasn't as much as ran the length of myself since High School. I have always enjoyed swimming and have been lucky enough to own horses most of my life. However.......... since children came along I have had less time for these activities and over time although not way overweight, I have become a little soft! Looking forward to trying this and my super fit sons (15 and 12) say they will run with me. Actually quite excited about it all particularly determined as hubby says he'll believe it when he sees it lol lol.
