All four flat women's sprint events - 60, 200, 400, 4x400 -- featured collegiate records and one of the two fastest times ever run indoors.

Roisin Willis & Juliette Whittaker powered Stanford to the DMR title and both will be back for the 800 final on Saturday.

Beatrice Chebet, Jacob Kiplimo, and the sport of cross country were the big winners Down Under.

Josh Kerr had a big run and Chase Ealey a big throw, but when this was all over we were wondering, "Is the OAC the top group in America?"

Nuguse smashed Bernard Lagat's American record by 2+ seconds and is now #2 all-time indoors, behind only Yomif Kejelcha. Nuguse is so good Jonathan Gault says Olympic gold is his ceiling.

Hodgkinson had to hold off the surprising 37-year-old Noelie Yarigo. Tsegay's time was #2 ever indoors, bumping Elle St. Pierre to #3.

None of the top six finishers in the women's race had made a Worlds team before. 3rd through 7th in the men's race were separated by 0.8 of a second.

Sisson ran 66:52 to take 18 seconds off her own record but finished 2nd to Ethiopia's Hiwot Gebremaryam. Tirunesh Dibaba was never a factor in her return and was 16th in 71:35. In the full marathon, Hitomi Niiya (2:19:24) nearly broke the Japanese record.
