Head to Tucson for this fun event where you can choose your challenge: tackle a 5K, 10K, or half marathon, all starting at 8:00 AM. Make sure to register online through RunSignup ahead of time (on-site registration isn't offered), arrive early for packet pickup during the 30 minutes before the race, and plan to cross the finish line within 3 hours and 30 minutes to earn your medal. Beyond the finisher medals, you'll enjoy a shirt and gear shop, costume contest awards, and the chance to earn series points.
