Head to Tucson, AZ for this race where you can pick your distance—5K, 10K, or half marathon—all kicking off at 8:00 AM with packet pickup 30 minutes early (wrapping up 10 minutes before start time). You'll need to sign up in advance through RunSignup since day-of registration isn't available, and you'll have 3 hours and 30 minutes to finish your chosen distance on out-and-back courses. The 5K and 10K runners will cover the same route (once or twice depending on distance), while half marathon participants will complete a different out-and-back loop four times.
