Harry Potter: new mage

Harry noticed that he was fast weirdly fast so he did a test. He went and ran 100 meters in 28 seconds when actively focused on his speed, and 47 when he ran focused on school. Which when he looked it up no 6 year should run 100 meters in 28 seconds when they haven’t trained. His speed is being boosted and he doesn’t know why. Hi so this is my first attempt at a story it’s not going to be good but I’ll try. Is you have suggestions on it I’ll try to look at them but I have school and stuff sorry if I don’t upload or look at this for weeks. If any one actually reads this.
