Marileidy Paulino wins the league, but the victory is decided in one race

Marileidy Paulino has maintained an undefeated record in the 400-meter events throughout the current Wanda Diamond League season. Despite this consistent performance, her status as the circuit champion for 2026 remains uncertain.

The uncertainty stems from the specific competition format of the Wanda Diamond League. Under these rules, dominance throughout the preliminary races does not automatically secure the overall title, as the final championship is determined by the outcome of a single decisive race.
