The annual Fun Run is coming up at Brookside Elementary! The students will all run laps around the carpool lane, and Miles Lewis wants to be one of the top five runners. Even though he zooms through sprints, he runs out of gas for long distance, so he creates a nutrition and exercise regimen to boost his endurance. But on the big day, he witnesses one kid struggling to keep going. Should Miles keep pressing for his personal best, or should he lend support to help a friend? In the end, Miles must decide what winning really means to him.
