Meet Spencer, the official dog of the 126th Boston Marathon.

After two years, the Boston Marathon was finally back to normal. With a cancellation in 2020 and a limited capacity in 2021, the world was excited to see this historic race back to its regular schedule. And perhaps no one was more excited than Spencer, the beloved Golden Retriever who has been lending support to racers since 2015.

 This therapy dog is a fan favorite and racers line up to get their picture taken with him. 

In fact, he's become so synonymous with the race that the Boston Marathon named him the official dog of the 126th Boston Marathon.
