The sixth-fastest American woman ever in the marathon will be joined Sunday in Chandler, Arizona, by five of the top 10 men's finishers and four of the top 10 women's finishers from the U.S. Olympic Trials marathon for The Marathon Project 2020, an event custom-made for quick times over the 26.2-mile distance.

Live coverage will begin at 9:45 a.m. ET on USATF.TV+ with commentary from Paul Swangard, Desiree Linden and Bernard Lagat. There will be a 90-minute replay of the race on NBCSN in primetime from 8-9:30 p.m. ET.

Runners will traverse a 4.26-mile loop six times, taking advantage of what the organizers call, "some of the flattest, most pristine roads you could ever imagine." Chandler is due for sunshine on Sunday and temperatures ranging from 37 to 67 degrees, with low humidity and very light winds.

Runner-up at the London Marathon in October with a lifetime-best 2:22:01, Sara Hall leads the women's entrants and will face a tough challenge from Kellyn Taylor, the No. 8 American all-time, and Emma Bates, who holds the No. 10 spot on the list. Taylor is coming off a PR in the 10,000m at The Track Meet on Dec. 5, where she clocked 31:15.65.

Stephanie Bruce, who was sixth at the Trials and finished ahead of Bates and Taylor, also notched a 10K PR behind Taylor in that race and has the fourth-best marathon PR in the field. The other top-10 finisher from the Trials, Julia Kohnen, won the USATF marathon title in 2019 at the Twin Cities race and had a PR 2:30:43 at Atlanta.

Medical student Martin Hehir is the top Trials finisher in the men's race, taking sixth in Atlanta, but there are a bevy of contenders who will be seeking a sub-2:10 finish. 2016 Olympic sixth-placer Jared Ward is the most decorated entrant, sporting a legal best of 2:10:45 to go with his pair of sixth-place efforts in the NYC Marathon in 2018-19. Ward ran 2:09:25 for eighth at Boston last year, one place behind Scott Fauble, who crossed the line in 2:09:09 on the aided course.

CJ Albertson, seventh at the Trials, has also recently broken 2:10... on a treadmill. The three men who finished behind him in Atlanta, Jonas Hampton, Collin Bennie and Matt McDonald, will need to cut two minutes off their lifetime bests to bust 2:10, but nothing is out of the question in 2020. They will have strong international competition from Eritrea's Amanuel Mesel, a 2:08:17 man who was third at Houston in January, and Mexico's José Antonio Uribe, who was fourth at Houston and boasts a 2:08:55 PR from 2014.

At the end of a dismal year for national and international athletics competitions due to the Covid-19 pandemic, The Marathon Project will be a welcome event for many of America's top distance runners, who will also be chasing prize money for the top three finishers in each race. The winners will receive $5,000, while the runners-up get $2,000 and the third-placers get $1,000. Pacers will be available to help pull the men under 2:10 and the women under 2:24.
