It's great she is into sport. Healthy lifestyle. I frequently pass by a running track which is really good and often wish I could pluck up both the fitness and courage to run or at least jog. I found out a while back I have the "sprinter" gene, which means I can run fast and know it's true. I am unfit though and certainly not young and didn't do running as a sport when I was young but was always drawn to it. I waw told as a young child I used to fly off at top speed in park and parents had terrible time catching up. You are lucky to have such healthy children who love sport.
