A runner is like a superhero who can move really fast using their legs. Imagine if you had super-speed shoes that let you zoom across the playground quicker than anyone else. This is what a runner does, but with their own strength and energy. They can race in competitions to see who is the fastest, like a cheetah racing against the wind.
Think of a runner as a train on tracks. Just like trains go from one station to another, runners move from one place to another using their legs. They need to keep going without stopping, like a train chugging along the tracks. They have to practice a lot to be strong and fast, just like how a train needs fuel to keep moving.
Imagine a wind-up toy that you twist and then it zooms off. Runners are like that toy, full of energy and ready to go. They have to eat healthy foods, like fruits and vegetables, to keep their energy up and stay strong. With each step, they get closer to their goal, just like the toy getting closer to the end of the table.
