Head to Kansas City for Medal Madness, where you can choose between a 5K, 10K, or half marathon starting at 8:00 AM—just make sure to register ahead of time on RunSignup and pick up your packet 30 minutes to 10 minutes before the race begins. The 5K and 10K both use repeated loop courses (the 5K doubles a 0.78-mile loop while the 10K quadruples it), and the half marathon circles a 1.09-mile loop six times, giving you 3.5 hours to cross the finish line. All finishers earn a medal, and you'll have the chance to shop gear, compete for costume awards, and rack up series points.
