The runners from the international torch relay met up with the kids at Hayford Park in Bangor on Wednesday.
The relay was started in 1987, by Sri Chinmoy, a man who wanted to spread peace and understanding.
Participants in the North American leg already ran 10,000 miles by Wednesday. They started in New York in April, ran to Mexico and Canada, and then stopped in Bangor.
Kids got a chance to race with the runners and hold the ceremonial torch.
"It felt like I was holding a bunch of peace in my hands," said Madison Kearns, one of the campers. "It feels like love in my heart."
The peace run has been to more than 150 countries, and participants said at any one time there's a peace run going on somewhere in the world.
One runner, from Australia, said they meet all sorts of people, but especially enjoy spreading their message to kids.
"The flaming torch is a symbol of aspiration that everybody carries in their hearts for peace," said Sirinyu Peirson. "The peace run is about sharing the message that peace begins with individuals and giving people an opportunity to bring that forward."
The kids sang songs and played games with the runners, but one of the camp leaders said the kids' favorite part was guessing where the international runners were from. She also said the fun summer day had a deeper meaning.
Katelyn Wright, the assistant program director with Kid's Cave, said the day was really, "to start them out young thinking about peace and how we can be kind to each other, and really do their own little part of making the world a better place."
Next the runners will travel through New Hampshire and Massachusetts, before finishing back up in New York.
