Dos Santos and Russell set hurdles world records in Zurich

Brazilian Alison dos Santos broke the world record in the men's 400 metres hurdles with a time of 45.80 seconds. American Masai Russell broke the world record in the women's 100 metres hurdles with a time of 12.09 seconds. Both marks came at the Weltklasse Zürich meeting in Zurich, Switzerland. The report names the athletes, the events, the times, and the meet.

A world record replaces the previous best legal time in that event. The note states the new times. It does not print the old records they broke. It does not describe wind readings. The claim is that each performance is a world record.

The men's race is one lap of hurdles. The women's race is the shorter sprint hurdles. They are different events, and the times are not comparable with each other. Each record belongs to its own race. Both happened at the same meeting.

Weltklasse Zürich is a major athletics meet. Zurich is the city. The report does not give finishing positions behind the winners. It focuses on the two record performances. No false start is mentioned.

Dos Santos is identified as Brazilian and Russell as American. No age is given. No reaction from a federation is included. The sporting facts are the names, the nationalities, the events, and the times 45.80 and 12.09 seconds.

Other results from the meet are not listed in this note. The news is the pair of world records. One is the men's 400 metres hurdles. The other is the women's 100 metres hurdles. Both were set in Zurich.
