Czech women's 400-m record broken


Czech women's 400-m runner Zuzana Hejnova has broken the Czech national record at the World Athletics Championships in Osaka, Japan. The 20-year-old's time of 55.04 seconds in the semi-final of the event on Tuesday knocked nearly eight tenths of a second off the previous best Czech time in the discipline. Unfortunately, Hejnova's performance was not good enough for her to qualify for Wednesday's final.
