El Tour de Tucson stands as Arizona’s largest participative cycling event, drawing nearly 7,500 cyclists from around the globe to Tucson the Saturday before Thanksgiving. This 40+ year tradition brings together riders of all abilities for an experience that blends challenging desert terrain with a deeply charitable mission that has raised millions for nonprofits since 1983.

The crown jewel Century Ride covers 102 miles with over 2,800 feet of elevation gain, starting at 7:00 am from the Tucson Convention Center. The route winds through iconic Southwestern landscapes including Davis Monthan Air Force Base, Old Spanish Trail, and historic Colossal Cave, showcasing the signature saguaro cacti and mountain ranges that define the Sonoran Desert. The Metric Century (63 miles, 1,600+ feet climbing) and Half Metric Century (32 miles, 500+ feet) offer shorter challenges for developing riders.

November’s crisp desert mornings create ideal riding conditions, though participants often queue from 4:00 am in thrift-store sweatshirts later donated to charity. The event’s unique Platinum Designation recognizes elite riders who’ve proven pack-riding skills through qualifying times or racing credentials, allowing them to start together safely.

Aid stations appear every 7-12 miles with nutrition, mechanical support, and volunteers, though they operate on strict schedules with a 4:30 pm course closure. The post-ride Casino del Sol Expo & Fiesta features live music, local food, and a beer garden where thousands of participants celebrate their achievement in true desert community spirit.
