Head to Conway, NH for a 5K that you can run, jog, or walk while giving back to the Conway Area Humane Society—you're welcome to bring your own dog, go it alone, or volunteer to run alongside a shelter pup. The out-and-back course starts at Tuckerman Brewing Company, and registration costs $35 early or $40 on race day ($10 for kids), with the bonus that bringing a shelter supply item gets you a free beer. The race kicks off at 8:30 a.m., and afterward you can enjoy food and drinks at the brewery until 11:30 a.m., just remember to keep your dog on a 6-foot fixed leash and limit yourself to one pup per person.
