Stanford, California - Selemon Barega returns to defend his 2-mile title in the Prefontaine Classic.

That's good news for fans and bad news for the rest of the field. In addition to his Pre Classic 2-mile victory last year, he was merely 18 when finished No. 1 in the Track & Field News annual world rankings for 2018.

He leads an incredible field that includes seven of the world's top 9 5k runners in the T&FN rankings. Amazingly, three in the field (including Barega) are still eligible for World Junior (U20) records.

The 2-mile distance is a short race for the world's best 5k runners. The Pre Classic 2-mile record of 8:03.50 - set in 2007 by Australian Craig Mottram - remains the fastest run on U.S. soil.

Barega achieved his most impressive performance last summer by winning the Diamond League 5k title in 12:43.02, a time bettered only by the last three world record setters - two of whom ran before he was born. He led a 1-5 Ethiopian sweep that included two former Diamond League champions.

Barega - now 19 - first came to prominence in 2016 by winning the world Junior 5k gold, then made the London World 5k final as a 17-year-old - his 5th place finish matched his first T&FN world ranking at No. 5 - before taking World Indoor silver last year as the 3k's youngest-ever medalist.

Earlier this year Barega displayed a longer side, finishing 5th in the World Cross Country Championships in March. Last month, he won the Ethiopian 10k title in his debut at the distance, running 28:23.7 in the very high altitude of Addis Ababa (7697 feet/2346m).

Paul Chelimo, 27, is the only racer in the field with medals in the 5k from Rio and the London World Championships. His Olympic 5k silver was the first medal by an American since Bob Schul won the 1964 Tokyo Olympics. In London, Chelimo matched the blazing final lap of gold medalist Muktar Edris and was edged out of a silver by legend Mo Farah for a bronze.

He racked up his third-straight top-4 world ranking by T&FN last year - the first time an American has had three consecutive top-4 ranked seasons. Chelimo is No. 4 all-time American in both the 5k and 3k. He was 2nd in last year's Pre Classic 2-mile, and his radar includes the American best of 8:07.07 set by Matt Tegenkamp in the 2007 Pre Classic.

Bahrain's Birhanu Balew, 23, made his first T&FN world rankings last year at No. 2. He was the only runner to beat Barega on the Diamond League circuit last summer and finished 3rd in last year's Pre Classic 2-mile. He won his first Asian Championships gold in April in the 5k.

Abadi Hadis, 21, also made a 5k debut in the T&FN world rankings last year, but his No. 5 wasn't his first world ranking - he world ranked in No. 7 in the 10k in 2017 after an initial ranking of No. 10 in 2016. His 10k PR of 26:57.88 in 2016 is still second best on the all-time world Junior list. The Ethiopian was bronze medalist in the 2017 world cross country championships and nearly matched his sub-13 5k PR in Rome this weekend - three months after equaling his half-marathon PR of 58:44.

Ethiopian Hagos Gebrhiwet, 25, was the Diamond League champion in 2016 and is tied for the most T&FN world rankings in the field with five - starting in 2012 at age 18. He also has the field's most major medals with three - bronze in Rio and the Beijing Worlds after a silver in the Moscow Worlds. He was the previous world Junior record holder in the 5k and still holds the indoor 3k record. This weekend he ran 12:54.92 in the Rome 5k a week after debuting in the 10k at 27:01.02.

Canada's Mo Ahmed, 28, lowered the Canadian 5k record into sub-13 territory with a 12:58.16 late last week. He has been world-ranked by T&FN five times, matching Gebrhiwet for most in the field. The last two years Ahmed has ranked in two events, and his No. 2 in the 10k last year matched the best ever by a Canadian long-distance track runner since Bruce Kidd's No. 2 in the 1962 5k. Ahmed just missed a medal in Rio, finishing 4th in the 5k behind Gebrhiwet. The Wisconsin grad is Canada's record holder at 3k, 5k and 10k as well as the 2-mile.

Getaneh Molla, 25, made his first T&FN world ranking last year at No. 8 in the 5k and earned a silver in the African Championships. This year he has embarked on longer journeys, starting with a debut in the marathon at 2:03:34 to win in Dubai in January to make him the fourth-fastest Ethiopian of all-time. Last year Molla was 5th in the IAAF Half-Marathon World Championships and won Colorado's BOLDERBoulder 10K.

Henrik Ingebrigtsen, 28, will watch his two younger brothers - Filip and Jakob - try to break his family record of 3:50.72 in the Bowerman Mile as the trio continues to fascinate fans well beyond the borders of Norway. Henrik has the most European medals in the family with seven - starting with a gold in 2012 (1500) and most recently a bronze in March (3k). His 5th place in the London 1500 is the best Olympic finish by a Norwegian in that event. He set the national 2-mile best in last year's Pre Classic at 8:22.31.

Fastest in the field is Ronald Kwemoi, 23, with a 3k best of 7:28.73. The Kenyan is also the fastest miler in the field at 3:49.04, which he ran winning the 2017 Bowerman Mile. His 1500 best dates back to 2014, when he clocked a staggering 3:28.81 that still stands as the world Junior record. He missed most of last year, but was world ranked by T&FN the four previous years in the 1500/mile, including a No. 4 in 2017.

Joshua Cheptegei, 22, of Uganda won the world cross country championships in March and was silver medalist in the London World 10k. He was No. 1 in T&FN's 10k world rankings last year and is Uganda's second-fastest runner at 10k and 3k. He swept 5k/10k gold at last year's Commonwealth Games.

Fellow Ugandan Jacob Kiplimo, 18, made it a 1-2 sweep of medals at the world cross country championships. He won the Junior race in 2017 when it was held at home. Last summer he earned silver in the world Junior 10k after a bronze in 2016. Last month he won the Great Manchester Race road 10K by almost a minute in 27:31.

Ethiopia's Milkesa Mengesha, 19, won this year's world Junior cross-country title. Last month he debuted in the 10k, taking 4th in the Ethiopian championships at 28:49.2 at high altitude. Two weeks earlier he won a Swiss road 10K in 27:47.

Stewart McSweyn, 24, became Australia's second-fastest at 5k and 3k last year, following Mottram on both all-time lists. In February he ran 3:35.10 indoors, fastest under cover by anyone ever from Oceania.

Justyn Knight, 22, is Canada's second-fastest 5k runner after Ahmed. He won last year's NCAA indoor 5k and the 2017 NCAA cross-country title while at Syracuse.

Richard Yator, 21, ran a late-season world-leading 10k 27:14.70 in Japan last October. The former World Youth (U18) gold medalist at 3k set his 5k best of 12:59.44 in last year's Diamond League final.

Paul Kipngetich Tanui, 27, earned Olympic silver in Rio at the 10k and took a third-straight World Championships bronze last summer in London. He has more than 100 laps of Pre Classic racing in his career.

Breaking News - Yomif Kejelcha, 21, who shattered the world indoor mile record in March at 3:47.01, has been added to the Bowerman Mile field. The Bowerman Mile record is 3:47.32 by Ayanleh Souleiman, who is also in the race.

The Prefontaine Classic is the longest-running outdoor invitational track & field meet in America and is part of the elite IAAF Diamond League of meets held worldwide annually. Sponsored by NIKE continuously since 1984, the Pre Classic will be shown live to an international audience by NBC.

Stanford University has a proud track & field tradition that dates back to 1893. In addition to its 922 All-America honors, 64 Olympians, and four NCAA team titles, Stanford has played host to important meets throughout its history, including the 1941 NCAA Championships, 1932 and 1960 U.S. Olympic Trials, and the epic 1962 USA-USSR dual that has been described as "the greatest track meet of all time." After the facility was renovated in 1996, Cobb Track & Angell Field has been the site of the 2002 and '03 U.S. Championships and is annually home to the Payton Jordan Invitational, the nation's premier distance running carnival.

Steve Prefontaine is a legend in the sport of track & field and is the most inspirational distance runner in American history. He set a national high school 2-mile record (8:41.5) while at Marshfield High School in Coos Bay, Oregon, that is the fastest ever in a National Federation-sanctioned race. While competing for the University of Oregon, he won national cross country championships (3) and outdoor track 3-Mile/5000-meter championships (4), and never lost a collegiate track race at any distance. As a collegiate junior, he made the 1972 U.S. Olympic Team and nearly won an Olympic medal, finishing 4th in the 5K at the 1972 Munich Olympics, at age 21. After finishing college in 1973 and preparing for a return to the Olympics in 1976, he continued to improve, setting many American records. His life ended tragically on May 30, 1975, the result of an auto accident, at age 24. The Pre Classic began that year and has been held every year since.
