About the race

The Marathon Project is a December marathon weekend held in Chandler, Arizona. The event uses a flat, fast, multi-loop course that is described as designed for record attempts and personal best performances. The event brings together professional athletes, ambitious amateurs, and members of the global running community.

The weekend program includes a professional field with elite entry requirements and pacers set up to support world class times and Olympic Trials standards. A separate Gold Wave offers a premium amateur experience with dedicated professional pacers for finish targets from 2:20 to 3:30, plus personal bottles for each competitor and indoor warm-up space. Support features listed include personal fluid stations and professional pacing groups.

A festive 5K called the Cowboy Christmas 5K is part of the weekend and benefits the LovePup Foundation. The event materials also list course records for the marathon distance and note partners and sponsors involved in the event.
