In the final Laura Muir (Great Britain) made her way to the front to set the early pace, marked closely by the Olympic champion Faith Kipyegon (Kenya). After a 2:17 first 800 metres, Kipyegon took the lead. After running at the back of the pack, marking world record holder Genzebe Dibaba (Ethiopia), Sifan Hassan (Netherlands) ran around the field into the lead. who lead until the final straight, when Kipyegon regained the lead. Hassan held the lead into the final lap, with Kipyegon on her shoulder. Hassan would not let Kipyegon by, keeping her on the outside. Muir tried to stay on the back of the leaders, with Dibaba temporarily joining. Jennifer Simpson and 800 metre star Caster Semenya rushed to keep up, while Dibaba disappeared from contention. Sprinting the entire last lap, Hassan held the lead until the final straightaway when Kipyegon was able to edge ahead. Hassan began to struggle as Muir tried to chase Kipyegon on the outside. Simpson was sprinting down the inside rail while Semenya was behind her but free from traffic on the far outside. Simpson had nowhere to go until Hassan drifted to the outside of the first lane, opening a small gap which Simpson squeezed through. Now with clear running room, Simpson ran past Muir just a few meters before the line to get silver, just behind Kipyegon. On the outside, a step behind Simpson's rush, Semenya dived at the line to nip Muir for the bronze.
