The IAAF Diamond League will make its only U.S. stop this weekend with the 43rd Prefontaine Classic in Eugene, Oregon. The strong fields, with international stars as well as top American runners, preview of some of the likely matchups at the Olympic Games in August in Rio. 

The meet runs over two days, Friday, May 27 and Saturday, May 28. On Friday, known as “Distance Night,” the best events are the women’s 5,000 meters and the men’s 10,000 meters. 

Those races will be broadcast live on USATF.TV at 11:20 p.m. ET/8:20 p.m. PT, but viewers will need a +PLUS account. (A monthly pass runs $12.99, it’s $119.88 for a year, and $199.92 for two years.)  

Here’s what to watch: 

Women’s 800 meters
The field will be entirely American runners, five of whom have run faster than two minutes. Five-time U.S. champion Alysia Montaño headlines the field that includes world indoor gold medalist Chanelle Price, Laura Roesler, 2014 NCAA 800-meter champion, and Kate Grace, who has run the fastest American time so far this year.

Women’s 5,000 meters 
Molly Huddle, the American record holder, will face Ethiopia’s Vivian Cheruiyot, the most decorated veteran in the field with multiple Olympic and world championships medals. Sally Kipyego of Kenya, who lives and trains in Eugene and was the 2012 Olympic silver medalist at 10,000 meters, is also in the race. 

Men’s 10,000 meters
British star Mo Farah, double Olympic gold medalist at 5,000 meters and 10,000 meters in 2012 and winner of the same two events at the 2013 and 2015 world championships, will run. He should see competition from Stephen Sambu of Kenya, who has a best of 26:54.61 at the distance. Chris Derrick and Eric Jenkins are the top Americans. 

Saturday

Saturday’s events will be broadcast on NBCSN (3:30 ET/12:30 PT) and NBC (5:00 ET/2:00 PT) or available online at NBC LIVE Extra. Canadian viewers should check CBCSports.ca and British viewers can watch Saturday’s events on the BBC. Here are the most intriguing races: 

National Mile
The race features two high school standouts, Michael Slagowski and Austin Tamagno. Slagowski is the newest high schooler to break the four-minute barrier. The Rocky Mountain High School senior from Meridian, Idaho, ran 3:59.53 at the Jesuit Twilight Relays in Portland on April 29. 

Tamango, a senior at Brea Olinda (California) High School, decided to forgo his high school sectional and state meets to compete at the Pre Classic. Although he hasn’t run a sub-4:00, he ran 3:44.14 for 1500 meters last weekend (which converts to a 4:02 mile). 

Pro Americans in the field include Leo Manzano, the 2012 Olympic silver medalist in the 1500 meters, and Andrew Wheating, the 6-foot-5 former NCAA champion and two-time Olympian. 

Men’s 800 meters
In the men’s 800, 2016 world indoor champion Boris Berian of the U.S. will face Nijel Amos, the 2012 Olympic silver medalist from Botswana. Mo Aman, the 2016 Pre Classic winner and Ethiopian record holder, looks to defend his title. Four runners in the field have run times faster than 1:43.

Women’s 3,000-meter steeplechase 
The race features three top U.S. women: Emma Coburn, who has a personal best of 9:11:42, Leah O’Connor, the 2014 NCAA champion, and Ashley Higginson, winner of the 2015 Pan American Games. They’ll be competing against five Kenyans, including Hyvin Kiyeng, the 2015 world champion who ran a world-leading 9:07.42 in the event in Shanghai two weeks ago. 

Men’s 5,000 meters
American Bernard Lagat, 41, returns for his 16th Pre Classic. He’ll face the defending event champion, Yomif Kejelcha, 18, from Ethiopia. The event features notable Kenyans Geoffrey Kamworor and Caleb Ndiku, and top Americans Ryan Hill and Paul Chelimo. 

Women’s 1500 meters
Americans Jenny Simpson and Shannon Rowbury face off against each other for the first time this season and against top international talent, including Faith Kipyegon of Kenya and Dawit Seyaum of Ethiopia, who have already run sub-4:00 in 2016. Joining Simpson and Rowbury are Americans Treniere Moser, Brenda Martinez, and Alexa Efraimson. 

Bowerman Mile
The final event of the day will be the signature Bowerman Mile, which organizers are billing as the strongest field in the event’s history. The field includes five Olympic or World gold medalists as well as the top five finishers from last year’s world championships. Asbel Kiprop of Kenya, who has three world championship gold medals plus an Olympic gold medal, is the most decorated in the field, but his countryman Silas Kiplagat has edged him 3-2 in past matchups at the Bowerman Mile. 

Drew Hunter, a senior at Loudoun Valley (Virginia) High School, in February became the eighth U.S. high school boy to break 4:00 for the mile. In the race, he hopes to break Alan Webb's 2001 high school record of 3:53.43. The field also includes American steeplechase record holder Evan Jager (who has a 3:53.33 mile PR) and Ben Blankenship.
