Oh baby. We hope you are ready. Indoor track is BACK in a BIG WAY with action all over the US. In Boston, American Shadrack Kipchirchir wants to run the low 7:30s in the same race where the LRC singlet will be looking for a big PB. In NY, Ajee Wilson and Charlene Lipsey go for the AR and Robby Andrews and Clayton Murphy clash over 800.  In Seattle, these big names will be racing - Galen Rupp, Yomif Kejelcha, Shalane Flanagan, and Sifan Hassan. Plus marathoners Scott Smith & Aaron Braun chase sub-4:00.

Craig Engels is in the men's mile and Ajee Wilson and Charlene Lipsey in the women's 800. Courtney Okolo leads the springs, Ryan Whiting the throws and NCAA champs Karissa Schweizer and Ariana Washington are also competing.

The men's 1k is loaded as it included Murphy, Andrews, Wheating and Kidder.

There was no doubt who was the world #1 this year as Genzebe Dibaba had the greatest season ever for a women's 1500 runner. The battle for US #1 was more interesting as both Shannon Rowbury and Jenny Simpson had strong years. *Jenny Simpson Says Her Rivalry With Shannon Rowbury Is Good For Both Them And The Sport, Is Disappointed Lost Shoe Cost Her Opportunity For Medal at Worlds Simpson: "I was in the shape of my life [at Worlds] and I was really ready for the big moment and they just didn’t come together this yea. Ultimately, the run in Beijing was a heartbreaker for me. I put other priorities aside and put them all lower down the priority list for the sake of doing well in Beijing, so it was a real disappointment to not be able to race to my fitness there."  

Jenny Simpson and Shannon Rowbury both auto qualified to Tuesday's final but they are going to have their hands full as the African-born runners are looking great.

Hear what the world's best had to say following the first session at the 2015 IAAF World Championships

Johnson grew up in Indiana playing basketball and didn't take running seriously until her senior year of college. Now she's heading to Worlds.

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.

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.
