“You could see a few things that need to be worked on, but I actually think it’s a great idea.”
At the Düsseldorf meet, the organisers also measured athletes' jumps using the traditional board.
Mihambo’s “take-off zone” mark was almost half a metre better than her traditional result of 6.39, where she had four invalid jumps.
The 31-year-old, however, recorded a 7.07m jump under standard conditions in Karlsruhe on Friday and told reporters on Sunday she was “simply very tired”.
It is unclear whether World Athletics will introduce the new measure at major competitions such as the Olympics.
World Athletics president Sebastian Coe has advocated for changes, saying spectators get bored when athletes register invalid jumps.
Before Sunday’s event, Coe said in Düsseldorf “at the 2023 World Championships, around a third of the jumps were invalid”.
“Our sport is 150 years old. There are untouchable elements that we want to protect. But there are also areas that leave spectators cold”.
The reform has, however, faced criticism.
American great Carl Lewis, who won long jump gold at four straight Olympics from 1984 to 1996, called the plan an “April fools joke” on social media when the plans were announced in 2024.
Lewis said introducing a take-off zone “would eliminate the most difficult skill from the event”.
