The American 800m women took it to another level this week, and a Japanese runner reminded us the American men's marathoners have struggled as a whole.

A tangle of limbs on the final turn saw Brenda Martinez lose her momentum and Montaño fall to the track. Grace took advantage, riding the rail to victory in 1:59.10 as Ajee Wilson (1:59.51) and Chrishuna Williams (1:59.59) joined her on Team USA. Molly Ludlow missed out by an agonizing .04, taking 4th in her second consecutive Trials.

Ajee Wilson, Alysia Montano and Brenda Martinez have all starred on the international stage before. Will they make it to Rio? Not necessarily, as 12 Americans this year have run between 1:59.72 and 2:00.82.

Day 1 of the Pre Classic got underway with some mom power in the women's 800 and women's 5000m, and two no-names trying to take it to Mo Farah in the 10,000m.

What  year: Eliud Kipchoge ran 2:04:00 with his shoes falling apart, Genzebe Dibaba ran 3:50.07 with both her shoes, Bolt defeated Gatlin, and Montaño, Symmonds, Farah, and Cheserek kept winning.

Eunice Sum nabs the top spot as the only race she lost all year was Worlds. Our US #1 Alysia Montano cracks the world top 10.

Montano ended up 11th in 4:35.4.  

Montaño went down with 200 to go in her heat and her protest was unsuccessful so she'll sit out the semis and final. Molly Ludlow was only sixth but her heat was by far the fastest on the day and she made it in on time (2:00.70) while Brenda Martinez had to work for it in the final 100 after being boxed in. Ben True comfortably grabbed an auto qualifier in heat 1 of the 5,000 while Ryan Hill and Galen Rupp made it on time in a much faster heat 2.

Wit Ajee Wilson out, no one without internal testicles stands a chance against Eunice Sum, but should she be nervous give the recent CAS ruling? As for who medals behind Sum, it's wide open and our friend in Britain and Canada are dreaming of medal(s).

Before we start our World Championships previews, we thought it would be a good idea to take a step back and look big picture at what has transpired so far this year in the world of track and field. There have been a lot of amazing developments so far in 2015. We list five events that if we'd predicted them at the beginning of the year, you'd have said we were TOTALLY crazy.

Track events start on Tuesday and there will be some star power in the 100/200 with hometown phenom Andre De Grasse. The men's 5,000 (Cam Levins, Garrett Heath, David Torrence, Juan Luis Barrios) figures to be exciting, as does the women's 800, which features three sub-1:58 women, led by Alysia Montaño. Plus Andrew Wheating, Kyle Merber and Nate Brannen in the 1500, PPP in the TJ & David Oliver in the 110 hurdles.

We feel very confident in predicting one thing about the 800s. Ajee Wilson and Boris Berian are going to Worlds. After that, it's going to be a lot of fun seeing what happens.

There are quite a few contenders with five who have gone sub-2 this season in Ajee Wilson, Brenda Martinez, Alysia Montano, Chanelle Price, Molly Ludlow.
