Athing Mu is your gold medal favorite and American great Ajee Wilson did not make the Olympic 800m final.

It's time to get read for Worlds as they start on Friday. Wilson is the favorite for gold but might America sweep the medals and go 1-2-3?

Wilson is in the 600m while Craig Engels is in the 1000m with Johnny Gregorek and Sam Prakel. Natoya Goule vs Laura Roesler in the women's 1000m and Tuohy takes on the pros including Heather Kampf in the 3000.

For the third year in a row, Caster Semenya was undefeated but was this the last of her dominance?  Domestically, Ajee Wilson was the best of a strong group of US runners. Should US#3 Ce'Aira Brown be ranked in the world's top 10?

Can Ajee Wilson get the elusive gold medal? How does Raevyn Rogers do? Does Niyonsaba stay undefeated lifetime indoors?

Powell will line up in the 60 against World 100H champ Omar McLeod while Natoya Goule is in the 800. The 3000 has Emma Coburn vs Aisha Praught Leer.

Distance highlights included Jamaica's former NCAA champ Natoya Goule winning the 800 in 1:59.38 from Justine Fedronic (1:59.86) and Rachel Johnson taking the steeple in 9:46. In sprint action, winners included Asafa Powell (100 - 10.01), Queen Harrison (100H - 12.72), Steven Gradiner (400 - 44.62), Phyllis Francis (400 - 50.92), Jeshua Anderson (400H - 48.88) and Ashley Spencer (400H - 54.51). *MB: American Track League Atlanta Discussion Thread *Sanya Richards-Ross Carried Off Track After Pulling Up With Hamstring Injury It was also a rough day for DeeDee Trotter who had to receive treatment for an asthma attack and Lolo Jones who was a DNS with injury.

Chanelle Price shocked the world with her gold medal two years ago in Sopot. Can Wilson come through as the favorite on home soil in Portland?

Leah O'Connor will look to be the first woman to repeat in the steeple since Jenny Barringer in 2009. Shelby Houlihan will look to be just the third woman in history to win back-to-back NCAA titles in the 1500. Natoya Goule has won 3 NCAA titles but she faces a LOADED field.

Natoya Goule broke the meet record and Edward Kemboi ran faster than anyone else had at NCAAs in 14 years as the 800 action was fast.

McBride is looking to become the first man since fellow Canadian Nate Brannen ('03-'04) to repeat at NCAAs; Goule wants to regain her 2013 title after transferring from LSU to Clemson. Iowa State's Edward Kemboi (NCAA leader at 1:46.09) and Arkansas' Chrishuna Williams (2:02.95 in her first year as an 800 runner) lead the list of challengers.

Nice wins by Ajee Wilson and Jordan Hasay at the pro season got underway in full swing.
