From the start of the final, two Americans, defending champion Jennifer Simpson and super high-schooler Mary Cain bracketed the field and closed to fill in the front of the pack. But most of the pack stayed in close order formation throughout with much jockeying for position and flying elbows. Cain tried to stay on the curb but kept getting moved back as new suitors moved forward then fell back. Zoe Buckman came forward then went to the curb to suffer the same fate ahead of Cain. Throughout world leader Abeba Aregawi hovered near the front but not passing Simpson. With 300 to go, Aregawi went around Simpson and made a break for it. But Simpson and the rest of the pack didn't go away. Just 100 meters later, Simpson looked like she would go by, but Aregawi wouldn't let her by. Then Hellen Onsando Obiri moved up with momentum, but couldn't make her way around either of them. Aregawi gained a couple of steps around the final turn, but Simpson came back to make it a close finish. Obiri lost ground but held on to keep the bronze. Faith Chepngetich Kipyegon tried to hang on to her teammate but Hannah England made an impressive run from back in the pack to pass her on the inside to get fourth.[2]
