Who deserved the #1 US ranking took some thought as Ritz beat Meb in Boston and Luke Puskedra had the highest WMM finish of any American (5th) and fastest time of the year as well (2:10:24).

Mare Dibaba broke 2:20 and won Worlds this year so she deserves to be #1, particularly when you factor in she was also 2nd in Boston. Speaking of Boston, there, Desi Linden ran the fastest time on the year for the US and placed the highest of any American in a major this year.

Emily Infeld won the bronze but is she or Molly Huddle our world #3?

The Ben True-Galen Rupp-Ryan Hill debate was the toughest we had for any spot in any of our rankings this year. How did we pick between the 3?

Without a doubt, 2015 was the greatest year ever in the women's 5,000 thanks to Almaz Ayana and Genzebe Dibaba, who ran 6 of the 10 fastest times in history.

Two Americans crack the top 10. *LRC Coburn: "In general, [I was happy with 2015]. I wish I could have run a PR; that was a goal that I really wanted."

The men's 1500 may be the best event in all of track and field and yet Asbel Kiprop continues to find at way to get the job done. Is he now the GOAT? It also was a good year for Nick Willis, Matthew Centrowitz and Ben Blankenship.

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."  

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.

David Rudisha lost the most races of his pro career this year but he's our #1. We tell you why. How could we possibly rank Boris Berian as the US #1 when he didn't even make the final at USAs? Because Nick Symmonds told us to.

Conseslus Kipruto failed to medal at Worlds but the rest of his season was so good he earns the #1 ranking. *LRC Evan Jager Is "Extremely" Disappointed He Didn't Break 8:00 Or Medal This Year But Realizes He Made Big Strides Jager: "I feel like I made a huge jump in fitness from years prior. I took myself to a new level of athlete and really proved to myself that I was one of the best steeplechasers in the world and not just hoping I was one of the best."
