What The Marathon Project is
The Marathon Project began in December 2020 as an elite-only marathon on the Gila River Indian Reservation in Chandler, created to give professionals a race after many of the World Marathon Majors were canceled because of COVID-19.11 That race produced what was then the second-fastest American women's marathon, 2:20:32.9
It returned in 2025 as an annual event for both amateurs and professionals, on the same criterium-style course.9 The organizers describe it as a flat, fast, multi-loop course designed specifically for breaking records and achieving personal bests.1
The course records are 2:08:59 for men and 2:20:32 for women.1 The race's history page says the 2025 Gold Wave saw unprecedented amateur performances.5
Who can enter
The Gold Wave is the amateur race. It is limited to 400 participants, and anyone who has run under 3:30:00 for the marathon, 1:42:00 for the half marathon, 46:00 for 10K or 22:00 for 5K may register and will be accepted.6
The Professional Field is selected by the organizers and consists of 100 men and 100 women.6 The two official pages give slightly different standards: under 2:19:44 for men and 2:42:43 for women on the race site, and under 2:20:00 and 2:42:00 on the registration page.26 Shorter-distance marks are also considered.2
Athletes who have run slower than the professional standards are pointed to the Gold Wave.6 Registration for 2026 closes on November 30.6
The course
The race is run on the grounds of the Wild Horse Pass Resort in Chandler.4 The organizers describe the course as notoriously flat and fast, with six loops, designed for personal records.3
The criterium-style layout means spectators can see the athletes 12 times from a single vantage point.3 When the race returned in 2025, the loop was reported as 4.26 miles, run six times, with two large fluid stations on each loop.129
What Gold Wave runners get
The race markets the Gold Wave as a professional-style experience: personal bottles on the course, an indoor warmup area, a bag drop at the start, professional pace groups from 2:20:00 to 3:30:00, and a swag bag.2
The results suggest the format works for qualifying times. According to the race's press release, 81% of Gold Wave finishers in 2025 ran a Boston Marathon qualifier.4
For 2026, the professional race and the Gold Wave are being run together, which the organizers say is meant to maximize the energy on the course.4

The 2026 race is on Saturday, December 12.4 The marathon, for both the Gold Wave and the Professional Field, starts at 7:00 a.m., and the Cowboy Christmas 5K starts at 7:15 a.m., followed by awards and a post-race pool party.3 The registration listing shows a window of 7:00 a.m. to 1:00 p.m. for the Gold Wave and 7:00 to 10:30 a.m. for the professional race.7
