2021 Herculis

The 2021 Herculis was the 35th edition of the annual outdoor track and field meeting in Monaco. Held on 9 July at Stade Louis II, it was the sixth leg of the 2021 Diamond League – the highest level international track and field circuit.

On the women's side, the meeting was highlighted by Faith Kipyegon running 3:51.07 to beat Sifan Hassan and scare the world record. In the men's 3000 m steeplechase, the final lap warning bell was rung one lap early by race officials. This led Benjamin Kigen to start his final sprint early, thinking he only had 400 metres left to run when actually 800 metres remained. Upon learning of his mistake, Kigen slowed to a jog, allowing Lamecha Girma to pass and win the race.

Results
Athletes competing in the Diamond League disciplines earned extra compensation and points which went towards qualifying the Diamond League finals in Zürich. First place earned 8 points, with each step down in place earning one less point than the previous, until no points are awarded in 9th place or lower.
