- Mere seconds behind him was Yomif Kejelcha, who finished the race with a record that will likely outlast Sawe’s new world best: the fastest debut marathon in history.

- It’s 30% lighter than the previous version and the first sub-100g marathon super shoe, weighing just 99g, lighter than a banana or a bar of soap.
