Will having strong leg muscles make me run longer and faster?
That is a pretty good score, but you could do better. Having strong leg and calf muscles will help in general, but don’t overdo it. You should have just a very slim amount of fat to keep you insulated, but not enough to make you chubby! Make sure you get a good sleep two nights before a big race, i know it sounds weird but just trust me! You might not want a watch. It will just make you go slower because you think you are going too fast! Good Luck!
