Top Brits fighting for a Worlds spot include Jo Pavey, former NCAA champ Kate Avery, Andy Vernon and Dewi Griffiths.

In the past in Edinburgh, he's taken down the likes of Asbel Kiprop and Kenenisa Bekele. Now he's beaten Mo Farah.

Mo Farah's 2016 campaign and his quest for an Olympic repeat begins on Saturday morning in Scotland. He'll be challenged by 12:57 man Alemayehu Bezabeh as well as two-time Edinburgh winner Garrett Heath. The women's race includes Kate Avery, Emma Bates and Americans Amy Van Alstine and Rochelle Kanuho. Plus there is a relay race with loads of names - like Bush, Twell, Muir, Leslie, Masters, Jan Hannes and Grice. You can stream the race live on USATF.tv here, starting at 8 a.m.

The men's 800 (Rudisha vs. Amos Rematch + Berian and Loxsom) and mile (Kiprop vs. Souleiman as Centro, Leo and Blankenship try to go sub-3:50) are the crown jewels of the Saturday action. Other action includes Molly Huddle vs. Mercy Cherono in the 5,000, Eunice Sum vs. Brenda Martinez in the 800 and an African showdown between Isaac Makwala (#5 all-time) and Wayde van Niekerk (#11 all-time) in the 400.

Shalane Flanagan showed she's ready for Boston, Gabriele Grunewald got a nice pr and win in the 5000m, Sam Stabler of Lamar had the breakthrough of the meet in the 5000m, Oliver Aitchison showed he's becoming a force at 1500m,  German Fernandez got a much needed win and Erin Teschuk got some attention.

Stacked fields for every distance event. Also in the 10K field are Juan Luis Barrios, Futsum Zienasellassie, Fernando Cabada, Kemoy Campbell, Trevor Dunbar. More meet highlights include: Women's 10K: Shalane Flanagan, Dominque Scott, Kate Avery. Men's 1500: Lopez Lomong, German Fernandez, Stanley Kebenei, Andy Bayer (also listed in steeple). Women's 5000: Emma Bates, Juliet Bottorff, Tara Erdmann, Gabe Grunewald, Marielle Hall, Nelly Spence Gracey.

The Netherlands' Sifan Hassan will go for a distance double in the women's 1500 & 3000. France's Renaud Lavillenie is the favorite in the men's pole vault. The home nation will hope for 2014 World Indoor champ Pavel Maslak to lead a 1-2 sweep in the men's 400.

Erik Sowinski edged Robby Andrews, Ajee Wilson repeated, and Sally Kipyego won the 3000 as Ashton Eaton cold have killed himself.

What a meet. Shannon Rowbury looks to lead a NOP sweep in the women's mile while teammate Cam Levins shoots for the Canadian record in the 5,000. Mid-d studs Ajee Wilson (800) and Duane Solomon (600) will also feature. Plus Ashton Eaton (60 hurdles & long jump) will pull double duty.

We give Walt Drenth, Michigan State and Kate Avery the praise they deserve, plus talk Sarah Disanza, Emma Bates, Providence, and freshmen.

Kate Avery of Iona was clearly best and so were Walt Dretnth's Michigan State women at the 2014 NCAA Championships. Race Results Weekly recap with results.

Notre Dame has an extremely deep men's field (10 of the top 25, led by #10 BYU), but the best race of the weekend is Saturday in Seattle, where half of the men's top 10 (#2 NAU, #5 Portland, #6 Stanford, #7 Indiana, #9 Villanova) will square off. The women's races aren't as strong, but #3 Oregon vs. #4 Stanford at Washington should be compelling, with a potential debut from Stanford's Aisling Cuffe. In other action, the #6 FSU women trek up to Paul Short to face #5 Georgetown while the #1 Colorado men race at the Rocky Mountain Shootout.
*Aisling Cuffe Out For Most (Or All) XC Season With A Stress Fracture According to this blog post by one of the Stanford men.

The top returner is Emma Bates but she will be challenged by Aisling Cuffe, Kate Avery and Shelby Houlihan up front. Can Cuffe break the Foot Locker curse? Can a freshman (Elise Cranny or Sarah Baxter) crack the top five for the first time since 2009? We sort through a wide-open women's field as just 6 of the top 16 from NCAAs last year are back in 2014.

Senior Abbey D is the heavy favorite for NCAA title #8 in the 5,000, but who will win the wide-open 10k? Does super frosh Erin Finn have a chance? Or will veterans Emma Bates, Elinor Kirk or 2012 champ Juliet Bottorff come through?

Last year, Abbey D became the first American to ever win NCAA indoor crowns in the 3,000 and 5,000 in a career, let alone the same meet. She looks to repeat that feat as Laura Roesler looks to move out of Jordan Hasay's shadow. And a wide-open women's mile is there for the taking; might a steepler like Colleen Quigley win it?
