On Sunday, Tigst Assefa of Ethiopia shocked the running world by breaking the women's world record for the marathon by over two minutes. Assefa finished the Berlin Marathon in just 2 hours, 11 minutes, and 53 seconds.

But Assefa's record was far beyond what most people expected. After all, it was only her third time running a marathon.

"I wanted to break the marathon world record," she said, "But I couldn't imagine that it would result in a time under 2:12."

When Assefa was younger, she started by running short races, called sprints. Then she became a middle-distance runner, running the 800 meters (half mile) race. Her best time in the 800 meters was 1 minute and 59 seconds.

Last March, she ran her first marathon. Then last September, she entered the Berlin Marathon. She won, and set a new women's record for the course, finishing in 2:15:37.

This year, she ran almost four minutes faster than she did last year. In both races, Assefa ran faster in the second half of the race than she did in the first half.

Her time of 2:11:53 was over two minutes faster than the old women's record (2:14:04), which was set in Chicago in 2019 by Brigid Kosgei of Kenya.

When she finished the race, Assefa kneeled down and kissed the pavement before raising her arms in victory.

Though Assefa made it look easy, she said winning the race "…was the result of hard work" Assefa was coached by Gemedu Dedefo, who has helped train many Ethiopian star runners.
