Two Athletes Break Sub-2-HR Marathon in Adizero Adios Pro Evo 3 | Hacker News

Two runners broke the sub-2-hour marathon barrier in Adidas’s Adizero Adios Pro Evo 3, reigniting debate over super-shoe technology.

Yomif Kejelcha also ran sub-2 in his marathon debut, but did not win or set a record.

The discussion centered on lightweight, high-rebound racing shoes, especially how Adidas compares with Nike’s Vaporfly.

The result underscores how advanced footwear is reshaping elite marathon performance and raising fairness concerns.
