Distance run is missing

Had to reset my iPhone. After doing so my distance run option was gone...I know longer see it. I also had to re-buy the GPS part???!! Thought once you bought something it stayed. I like distance run on none training days. Other then that I love this app. Helped me train for my first 10k and my time was even faster for the actual race!!!
