Because of the lateWorld Athletics Championships, the Diamond League final was for the first time held before the World Athletics Championships.[4] Sixteen Diamond League champions (eight men and eight women) were determined and received wildcards to compete at the2019 World Athletics Championships. Thirteen more events were contested outside the Diamond League.
