In addition to his mother and Anna, it seemed that his friends at the university were watching Jake in the marathon, Jake had already said a few things about what happened to Aaron so Zack and William had no problem with him anymore.
As the three watched Jake's marathon they got closer and even talked and ate together and celebrated when Jake won and broke the world record, so things would be easier for Jake when he returned to approach the three.
When Jake returned nothing different had happened, some who liked marathons and followed the news about the evidence would know that Jake won in Chicago, but these people would probably already know Jake from other marathons.
Those most affected by this were the basketball team, Coach Smith and Coach Guthridge were impressed when they learned that Jake had won a big marathon again.
