2026 Frightening 4K

Haunting Downtown Anchorage! We’ve got treats, we’ve got costumes, and we’ve got a costume contest! Fall is here, and YOU will be haunting downtown Anchorage. We will be staging from the spooky Captain Cook courtyard. So grab your friends and family, don your best costumes and join us for a ghoulishly good time for all at the Frightening 4K. Fun and fantastic trick-or-treat stations will greet you at each kilometer. Fill up your candy bag, enjoy the spooky decor, or blast on by as fast as you can! Get your fill at the 4K, then head out and chase goodies all through downtown at the Anchorage Downtown Partnerships Trick-or-Treat Street! It kicks off right after the Frightening 4K. Family and Team Registration available! Families and teams of 3 members or more will receive $5 off of the registration fee once the third member signs up. The first two members will pay full price and then will each receive an automatic $5 refund once the 3rd member has joined!
