Runners run fast by having a diet of yam, bananas some energy drink such as lucozade, powerade or mountain dew. This also gives runners a load of energy so that they can run a long distances
In baseball a "point" is called a "run" One home run with no runners on base counts as 1 run. If there are runners on base each runner is counted as 1 additional run. There cannot be more than 3 runners on base. If a home run is hit with 3 runners on base the home run counts as 4 runs. Also when a batter gets a homer, the batter also counts as a run. EX: Runner on 1st, home run would count as 2 runs!
