This race has provided great atmosphere in the past and looks to again as Hunter faces Olympic Trials finalists Kyle Merber, Colby Alexander, Johnny Gregorek, Cory Leslie and more. Women's Field has Morgan Uceny, Sara Vaughn, Stephanie Brown, Nicole Tully, Heather Kampf.

What if a bunch of crazy stuff didn't happen at the Trials...

Molly Huddle, Emily Infeld and Marielle Hall are all coming back from the 10k and all three have a good shot to finish top-3 in the 5k. Huddle has said she's leaning against doubling in Rio, but Infeld and Hall haven't committed, so Nicole Tully, Abbey D'Agostino, Shelby Houlihan et. al could finish fourth (or even fifth or sixth) and still go to the Olympics.

The fields are strong once again for Sunday's late-night meet. Maggie Vessey (800), Cory McGee (1,500), Shelby Houlihan (1,500), Evan Jager (1,500) Henrik Ingebrigtsen (1,500), Sally Kipyego (5k), Nicole Tully (5k), Garrett Heath (5k), Chris Derrick (5k), Buze Diriba (10k), Molly Seidel (10k) and Sam Chelanga (10k) are among the entrants with the 10k track debut of Bernard Lagat.

Hunter would join Alan Webb as the only two high schoolers to go sub-4 indoors. Chris O'Hare and Cristian Soratos are also in the mile, Jordan Hasay, Nicole Tully and Emma Bates are in the 3000, Ajee Wilson, Morgan Uceny and Laura Roesler in the 800 with Robby Andrews in the men's 800.

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.

Other athletes announced for Millrose include Molly Huddle, Jordan Hasay, Eric Jenkins, Ajee Wilson, Ashton Eaton and Andre DeGrasse.

Wow. 8:19 final 3k to takedown Dibaba.

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.

Huddle was the only one to go with the rabbit and was still in contention with 100 to go, but lost out to the world silver medalist Cherono. In the steeple there was a fierce battle between Conseslus Kiopruto and Jarius Birech, Eunice Sum dominated the 800 and Nijel Amos and David Rudisdha finished only .10-seconds apart while Boris Berian went for it. In non-distance action, Renaud Lavillenie cleared 6-meters, Valerie Adams lost again and South Africa's Wayde van Niekerk blew the 400 field away. We recap it all here.

Ben True faces Olympic silver medalist Dejen Gebremeskel as he goes for the IAAF 5000 “A” standard. Chris Derrick and Eric Jenkins also racing. Lauren Johnson, Rachel Schneider go for the standard in the 1500 as they face Mary Cain andNicole Tully. Abbey D’Agostino and Emily Sisson in the 5000, Olympic bronze medalist Timothy Kitum, NCAA champ Edward Kemboi and Charles Jock in the 800.

A great race with a great finish and 3 new women going to Worlds.

Plus, have you ever heard of Hannah Fields? We didn't think so. Arguable America's biggest breakout performer in 2015, Fields nearly upset Nicole Tully in the race of the night - the women's Adro Mile. There were also wins for Ryan Martin in the 800 (1:46.74), Reed Connor in the 5,000 (13:34.68) and McKayla Fricker (Alexa Efraimson's training partner) in the women's 800 (2:03.57). Jonathan Gault has gone above and beyond the call of duty with this 3600 word recap. *MB: ROBBY ANDREWS IS BACK, BABY!! Crushes the field at the 20125 Adrian Martinez Classic

Matt Centrowitz thought it was a yawning matter, but no one else did, including Paula Radcliffe, Dai Greene, Nick Willis, Lornah Kiplagat and many others.

Mark Wetmore's two biggest stars will make their season debuts - Jenny Simpson (800) and Emma Coburn (1,500) - while Kara Goucher (5,000) will run her first track race since 2013 and Mary Cain will look to regain her "teen phenom" label.

The World Relays are gone until 2017, Stanford is in the books until next year, we take a deeper look at both and even go way back to the 1984 Olympic Trials 1,500 and a dive for the line by Chuck Aragon. Why? His daughter just ran a 4:16 1,500m in high school.
