Jakob is a seventh grade student attending P.S. 38. During Field Day, the final activity of the Fitness Zone, he ran with Marcus Goode, but they did not work well together. Jakob thought Marcus was going too slowly while Marcus believed the opposite. As a result, Chad Applewhite and Maya won the contest, scoring a hard-won victory for the sixth graders.

He is the fastest runner in the school, according to Goode.
