Since 1977, Grandma's Marathon has grown from a small gathering of 150 runners into one of the largest and most respected marathons in the United States. Today, the event draws more than 20,000 participants each June and generates close to $21 million in economic impact to the region—all while maintaining the warm, small-town atmosphere that makes it special.

The weekend's three-race schedule includes the iconic Grandma's Marathon, The Garry Bjorklund Half Marathon (established in 1991 and named after the race's first champion), and The William A. Irvin 5K (the weekend's traditional kickoff since 1994). Each race represents a unique opportunity to participate in or support a world-class running experience.
