The Diamond League announced four events (200m, steeplechase, discus and triple jump) will not be part of the main program in 2020. The decision comes after the Diamond League decided to scale the annual track circuit down to 24 events total (12 male, 12 female) to fit into a 90-minute time window. 

The 200m and steeplechase will still be included in five meets, but not the Diamond League final in Zurich. The triple jump and discus will only be featured in two meets.

The Diamond League said that the steeplechase, discus and triple jump scored at the bottom of research and surveys they conducted with fans. As for the 200m, “DL organisers felt would be too congested alongside the 100m, particularly in an Olympic Games’ year,” the release said. 

“Our objective is to create a faster-paced, more exciting global league that will be the showcase for our sport. A league that broadcasters want to show and fans want to watch. However, we understand the disappointment of those athletes in the disciplines not part of the 2020 Diamond League season,” IAAF president Sebastian Coe said.

Earlier in the year, the Diamond League announced that 2019 would be the last year for 5000m, though it will be replaced by the 3000m.  

The triple jump was assumed to be on the chopping block when the prospective cuts were announced. Top Americans Christian Taylor and Will Claye advocated throughout the summer to keep the event in rotation.

The loss of the 200m means that one of the sport's brightest stars, Noah Lyles, won't be able to compete in his best event at one of the biggest meets of the year. Lyles, the reigning 100m Diamond League champion, won gold at the World Championships and posted a 19.50 at the Lausanne Diamond League meet. 

Individual meets do have the option of staging additional events outside of the 90-minute broadcast window. A list of the events for the 2021 Diamond League will be announced at the end of the 2020 season.
