Costumes for Kids 5K & Halloween Fest Come for the race. Stay for the Halloween fun. Do it all for kids in foster care. The 12th Annual Costumes for Kids 5K & Halloween Fest takes over Prescott Courthouse Square on Saturday, October 24 for a morning of running, costumes, games, prizes, music, food, raffles and Halloween fun — all benefiting kids in foster care throughout Yavapai County. And you don’t have to be a serious runner to join us. Take on our challenging 5K through beautiful, historic downtown Prescott, or choose the 1-mile walk/fun run around Courthouse Square. Don’t want to run at all? Come for the festival! Enjoy carnival-style games and prizes, music from a live DJ, free food and snacks, raffles, costume contests for kids and adults, and plenty of Halloween fun. Costumes are encouraged but never required. Bring the kids, grab your friends, build a team or simply come out and enjoy the morning. Kids 16 and under and foster/kinship families participate FREE. Saturday, October 24 | 9 AM–12 PM Prescott Courthouse Square 5K begins at 10 AM | 1-Mile Fun Run follows
