Natalie and Elena Windels share both a last name and a passion for track and field. “I like how you just get to accelerate and, like, just use all your power and try and finish and do the best that you can,” Elena said. Her sister Natalie is more succinct. “I just like running,” Natalie said. James Pipkens, the head sprints coach for Apple Valley High School, works closely with the sisters. He says there may be some sibling rivalry going on.
