The Olympic bronze medallist at 10,000 is back to defend his crown but he'll face five other sub-2:07 guys in the field plus four really interesting debutantes: Yenew Alamirew (12:48/27:19 track pbs),  Birhanu Legese (59:20 to win New Delhi Half Marathon in November), Leul Gebresilase (59:18 HM), and Fikadu Haftu (59:22).

There are 10-guys who have gone under 13-minutes including Yenew Alamirew, Isiah Koech and Edwin Soi. Chris Derrick, Cam Levins, Hassan Mead, Paul Chelimo also in the field.

It was no contest as Farah took the 3000 in a world-leading 7:34.66 while Weightman held off US’s Gabe Grunewald to get her first big international win.

Farah has proven himself as the favorite for 5k/10k gold in Beijing but Bolt still has work to do to catch Justin Gatlin. Can he get closer in London? Farah faces Lopez Lomong & Bernard Lagat in the 3k, plus an American-heavy women's 1,500 featuring Lauren Johnson, Katie Mackey, Treniere Moser and many more.

Top Africans include Yenew Alamirew, Edwin Soi, Isiah Koech and Lawi Lalang. American Ryan Hill is also in the field.

Farah will face five men who have broken 7:31 including Hagos Gebrhiwet and Yenew Alamirew. The women's 1500 features '14 world leader Sifan Hassan and '13 world champ Abeba Aregawi, while Ethiopians Sofia Assefa and Hiwot Ayalew will race in the women's steeple. Justin Gatlin (100) and Allyson Felix (200) headline the non-distance action.

The first of the two DL finals should be spectacular as the winner of the men’s 800 and women’s 1500 likely will take home $50,000 and a spot into 2015 Worlds whereas second will get just a $6,000 consolation prize. Plus New Balance teammates Emma Coburn and Jenny Simpson try to bring home DL titles to the USA.

Jordan Hasay was last in the 1500 but still PR'd by over 2 seconds while the American men struggled in the 5000.

The two-day meet gets underway Friday and features top fields in the women's 1,500 and men's 5,000 as well as recent US champs Leo Manzano and Ajee' Wilson in the men's 1,500 and women's 800.

Hellen Obiri looks to keep winning against Abeba Aregawi and Jenny Simpson in the women's 1,500. Can Simpson get the AR or can Rowbury break 4:00? Asbel Kiprop takes on Nijel Amos and the 800 specialists and Emma Coburn goes for her second DL win in the women's steeple. Can she get the American record as well?

The field never went for a fast time, they went for the win as Rupp ended up 3rd.

A stacked field with the possibility of 2 more Americans joining the sub-13:00 club.

American Erik Sowinski has a great opportunity with the best 800m SB in the field.
