The Market Square Day 10K is a road race held in Portsmouth as part of the Market Square Day celebration. The event is a 10K course that winds through the streets of the city, offering views of downtown neighborhoods. The race typically draws about 1,000 runners and finishes at Strawbery Banke.
Event details
The starting line is in Market Square in front of the North Church. The race has been linked with the Seacoast Road Race Series since 2005; that series runs races ranging from 5K to 10K in communities across the Seacoast from May through November. Many streets in the downtown area are closed for the Market Square Day Festival, so parking in the area can be limited. The organizer is a 501c(3) nonprofit focused on events that support Portsmouth arts, culture and history. Sponsors for the 2026 event are listed by the organizer.
