I'm guessing that you're an aspiring baseball player. First off, a baseball travels as fast as you can throw it, and major league pitchers can throw a little over 100 miles per hour. There is no definite speed that baseball players run. They are often slightly faster than the average person, but if you can hit well, then you won't need as much speed. If you are in the 5-13 age range, bases are 60 feet apart and it is 45 feet from the pitchers' mound to home plate. From high school up, the bases are 90 feet apart, and it's 60 feet from the mound to home. Hope this helps.
