The 13th Annual Seacoast Cancer 5K is back and we’re running in Portsmouth again! The festivities will be held at the Mass General Brigham Cancer Institute at the Wentworth-Douglass Portsmouth Outpatient Center – located on the Pease Tradeport at 121 Corporate Drive, Suite 100 in Portsmouth, NH. Join us for that block-party feel while making an impact on local cancer patients and their families – and bonus – a much flatter 5K course!
