The 200m will in fact still be in the programme at 10 of the 15 Diamond League meetings and the discus and the triple jump will be contested at two meetings.
IAAF President Sebastian Coe said he understood the "disappointment" of athletes in the disciplines not included in the 2020 Diamond League season, but explained: "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." Triple jump, discus and the 3,000m steeplechase ranked "towards the bottom" in the research conducted, the IAAF said in a statement.
