The Nike Prefontaine Classic in Eugene produced two standout upsets on Saturday, as emerging teenagers claimed signature victories over decorated distance stars. In the Bowerman Mile, 20-year-old Dutch runner Niels Laros erased a 3.1-second deficit on the final lap to edge U.S. record-holder Yared Nuguse by one-hundredth of a second. Laros stopped the clock in 3:45.94, breaking the Netherlands national record, while Nuguse settled for second in 3:45.95. Earlier, 18-year-old Ethiopian Biniam Mehary captured the 10,000-metre race in 26:43.82, out-leaning Olympic silver medallist Berihu Aregawi by 0.02 seconds and holding off 2021 Olympic champion Selemon Barega. The results mark breakthrough performances for both Laros and Mehary, underscoring a generational shift as the world’s leading distance runners tune up ahead of the 2025 World Championships.
