Night 1 of the 2024 U.S. Olympic Track and Field Team Trials featured a host of top U.S. track and field stars vying to seal up their spots at the Paris Olympics, including Sha'Carri Richardson, Ryan Crouser and Athing Mu.

Richardson tripped on her shoelace out of the blocks but still rallied for a dominant win in her 100m heat, while Mu finished third in her first race of the 2024 season. Elsewhere on the track, Yared Nuguse, Shamier Little, and Michael Norman all advanced to their respective semifinals.

In the lone final of the night, Grant Fisher reigned supreme in the men's 10,000m to clinch a spot in Paris along with second-place finisher Woody Kincaid and Nico Young, who finished third. Fisher and Kincaid are both headed to their second Olympic Games, while 21-year-old Young is bound for his first.

Meanwhile in the field events, KC Lightfoot, who finished fourth at the Tokyo Olympics, failed to clear 5.60m and thus could not escape the first round. As a result, Lightfoot is out of Trials and will not compete at the Paris Olympics. Chris Nilsen, who earned silver at the Tokyo Games, and Sam Kendricks, the Rio Olympic bronze medalist, both advanced to the pole vault final.

In the men's shot put, Ryan Crouser, who will aim to win his third consecutive Olympic gold medal this year, advanced to the final alongside Joe Kovacs, who led the way with a 22.13m throw. Crouser had admitted to reporters earlier that he needed surgery for an ulnar nerve issue in his right elbow, and that he also tore a pectoral muscle. But the two-time Olympic champion is one solid night away from his third consecutive Olympic Games.

After one day, Heath Baldwin and Zach Ziemek are leading the men's decathlon, while Brooke Andersen and DeAnna Price set the pace in the women's hammer opening round.

Women's 800m Round 1

Defending Olympic champion Athing Mu headlined the women's 800m.

Allie Wilson prevailed in Mu's heat, edging the defending gold medalist in 2:01.57.
