On Sunday, Sept. 22, Throwback Brewery in North Hampton will host the Superhero 5K and Kids Fun Run, an annual celebration to benefit Rett’s Roost, an Ogunquit, Maine-based organization that runs weekend retreats for families that have experienced childhood cancer and child loss. The fundraising event will begin with a 3.1-mile race starting and ending at Throwback, followed by a kids’ fun run on-site shortly thereafter. During and after the race, there will be ample activities for all ages, including free kids crafts and games, face painting courtesy of Pixie Palette, balloon animals and a magic show with Sages Entertainment, a Kona Shaved Ice truck, fresh cotton candy and popcorn, a raffle and more. Adults 21 and over who complete the race will receive a free beer compliments of Throwback. And for the third year in a row, Alligator Wine will be playing a set of Grateful Dead covers immediately after the race. Visit rettsroost.org.
