Jordan Hasay

Hasay set the age 15 and national high school sophomore class records in the 3200m in her first race on the track in 2007 with a time of 10:04.52, the fastest high school time since 2004. She won the 3200 meter race at the 2007 CIF California State Meet in a time of 10:06.76 and won the mile race at the 2007 Golden West Invitational in a time of 4:43.34. Hasay also won the 1500 meter race at the 2007 USATF Junior Championship Track & Field Meet in a meet record time of 4:16.98. This was the fourth fastest HS 1500 of all time, the fastest ever by a US 15-year-old, fastest ever by a sophomore (eclipsed on June 1, 2012 by Mary Cain's 4:16.52), and the fastest HS time in 25 years. She received a silver medal in her first international championships, running a 4:17.24 in the 1500 meters at the 5th IAAF World Youth Championships in Ostrava, Czech Republic, finishing behind the 4:15.47 run by Sammary Cherotich of Kenya.

Hasay was selected by Track and Field News magazine as both the best high school miler and two-miler in 2007 (the first girls mile/2-mile double winner since Julia Stamps in 1997), and also the 5th best overall (and top sophomore) girls high school track and field athlete in the United States for 2007.

Hasay won the USATF Cross Country Championships Junior Women's 6K on February 16, 2008 in 20 minutes, 32 seconds at Mission Bay Park in San Diego.

At the 2008 CIF California State Meet on May 31, Hasay held off Davis Senior High School senior Laurynne Chetelat down the home stretch to win her third consecutive 3200 state title in a meet record of 9:52.13, the second fastest 3200 time run by a high school girl ever (only behind Kim Mortensen's National Record) and the first (along with Chetelat) under 10 minutes since Caitlin Chock in 2004. She successfully defended her national junior 1500m title on June 22.

In February 2009, Hasay committed to the Oregon Ducks over many other prestigious programs.

At the 2013 NCAA Women's Indoor Track and Field Championship, Hasay did not run the mile due to starting to focus on the longer distances. She placed second in the 3000m and fourth in the 5000m, leading Oregon to its fourth indoor title.

During her 2013 outdoor season, she ran 32:06 in her 10000m debut, getting third at the Payton Jordan Invitational to Shalane Flanagan and Kara Goucher. This time was only one second off the B Standard for the IAAF World Championships in Athletics in Moscow. She finished a disappointing 18th in the NCAA West Regional 10k, but won her heat of the 5k to advance to the NCAA Championships. In her last race in a Duck uniform she took third in the final of the 5000m, getting second to winner Abbey D'Agostino and Betsy Saina. Hasay was named 2013 Track & Field Scholar Athlete of the Year. Hasay finished her University of Oregon tenure as 18 time All-American.

After graduating from the University of Oregon in 2013, Hasay signed with Nike, Inc. and joined the Nike Oregon Project, to be coached by Alberto Salazar. She placed second in the 10,000 metres at the U.S. National Championships. Shortly thereafter, she ran a 31:46.2 10,000 meters, which was faster than the World Championships "B" Standard of 32:05 but slightly slower than the "A" Standard of 31:45. She earned a spot on her first senior World Championships team. After getting the standard, Hasay set a new personal best while finishing sixth in the 3000 meters at the London Diamond League meet. This was her international professional debut.

She set a school record and was part of two NCAA automatic qualifiers in her season debut at the UW Invitational. She broke the 3000m record by two seconds, winning in 9:05.42. She also ran the lead leg on Oregon's distance medley relay that won in 11:02.15. This mark broke the Dempsy Indoor Facility stadium record. She followed up that by running a nation-leading time in the mile at the Husky Classic, 4:34.75. At the MPSF Championships, she defended her title in the mile and tied for seventh place in the 800 meters. At the NCAA Indoor Championships, she led a 1–3–4 Duck finish in the mile to help Oregon capture its second national consecutive title. She broke the school record in the process. She came back the next day to hold off Villanova's Sheila Reid to win the 3000 meters. She also anchored the Ducks' runner-up DMR team, and broke the school record in 10:52.9. She was selected as the USATFCCCA's National Indoor Track Scholar-Athlete of the Year. With these two victories, she became the first person to win two Foot Locker Cross Country Championships and two NCAA Championships. That feat was duplicated in 2014 by Oregon teammate Edward Cheserek.

At the 2014 Payton Jordan Invitational she improved upon her personal best at 10,000, running 31:39.67. Her 10 km time is the 5th fastest in the world in 2014 according to IAAF as of July 11. Hasay is the second rated 10,000 meter woman (behind Shalane Flanagan) to qualify for 2014 USA Outdoor Track and Field Championships. At those championships, Flanagan did not run, but Hasay still came in second in 32:03.28, her kick unable to break a second surge by Kim Conley. Hasay later ran a personal best 1500 metres in 4:07.70 at a meet in Glasgow, Scotland on July 11, 2014.

Hasay placed third in the 2019 Boston Marathon with a time of 2:25:20.
