The 2020 United States Olympic Trials for track and field will be held in Eugene, Oregon. This will be the first major event for the redesigned and rebuilt Hayward Field. Originally, the event was to be held at Hilmer Lodge Stadium in Walnut, California. The stadium was due to construct $62 million in improvements in anticipation of the trials. That construction is potentially delayed due to multiple lawsuits by neighbors of the college. On May 1, 2018, USATF put the rights to host the trials back out to bid. On August 2, 2018, it was announced that Eugene, Oregon had been selected to host the competition. Organized by USA Track and Field, the ten-day competition is scheduled for June 19-28 and will serve as the national championships in track and field for the United States. The results of the event will determine qualification for the American Olympic team at the 2020 Summer Olympics, to be held in Tokyo. Provided they had achieved the Olympic standard, the top three athletes will gain a place on the Olympic team. In the event that a leading athlete does not hold the standard, or an athlete withdraws, the next highest finishing athlete with the standard will be selected instead. The trials for the men's and women's marathon will be held on February 29 in Atlanta and the trials for the men's 50 km race walk were held on January 25 at San Diego Christian College in Santee, California. The trials for the 20 kilometres race walk will be held on before.
