You’d be hard-pressed to find a tougher athlete than Kellyn on the pro running circuit. She’s a mom to daughter Kylyn, while at the same time running 100 miles a week and studying to be a firefighter. Yes, that’s right. When she finishes her running career she’s going to fight fires!

In 2012, Kellyn finished tenth in the 10,000 meters and qualified for the finals in the 5,000 meters at the U.S. Olympic Track and Field Trials. In 2013 she was fourth at the U.S. 10 Mile Championships (54:19), the top American at the Bloomsday 12k, she won the Green Bay Half Marathon (1:12:27), was sixth at the U.S. 5k Championships (16:01), won the Woodrow Wilson Bridge Half Marathon (1:13:02) and was fifth at the inaugural .US National Road Racing Championships over 12k (39:47). In 2014 where she was 4th at the USA XC Championships, won the NACAC XC Championships, won the Collegiate Running Association 10k title, won the GO! St. Louis Half Marathon (1:11:51) and won the USA 25k Championships. She also PR’d at 5,000 meters (15:21) and finished 5th at the USA Outdoor Championships. In 2015, she shot to the top of U.S. marathoning, running a 2:28:40 at the Chevron Houston Marathon. She went on to PR at the half marathon (1:10:59) later that year as well. Her 2016 began with a 6th place finish at the United States Olympic Trials Marathon. She then PR’d at 10,000 meters (31:40.70) before finishing 4th at the Olympic Track and Field Trials at the same distance. She also qualified for the finals in the 5,000 meters. She kicked off 2017 with a 3rd place finish at the USATF Cross Country Championships. In April she finished 13th at the Virgin Money London Marathon in 2:28:51. In the fall she ran her first TCS New York City Marathon and finished 8th in 2:29:56. She returned the track in January of 2018 and set a PR in the Indoor Mile (4:33.40) at the BU Terrier Invite. In the spring, after a disappointing DNF at the Boston Marathon due to historically bad conditions, she bounced back in a big way with a win,  a course record and a new personal best of 2:24:28 and the Grandma’s Marathon. In the fall she set a half marathon best of 1:10:13 to win the Rock ‘n’ Roll Las Vegas Half Marathon.

In 2019, she followed up a top-15 finish at the USATF Cross Country Championships and a win at the Pacific Pursuit 10k with an eighth-place finish at the United Airlines NYC Half. Then, in May, she was fourth at the Volkswagen Prague Marathon in 2:26:27. A brief summer season included a PR at 5,000 meters (15:19.23) and her first ever podium finish at the USATF Outdoor Championships–3rd place in the 10,000 meters. In the fall, she produced one of the biggest runs of her career–a 7th place finish at the TCS NYC Marathon in 2:26:52.

She kicked off 2020 by finishing in a tie for first place with teammate Stephanie Bruce at the Rock ‘n’ Roll Arizona Half Marathon. Then, at the Olympic Trials Marathon, she finished eighth in 2:29:55, despite running with a tibial stress fracture (diagnosed after the race). She returned to racing with a win at the KT Tape St. George Showdown over 5,000 meters in July, a runner-up at the Sunset Tour 5,000 in August, and a team/personal record of 31:07.60 10,000 meters at the HOKA Distance Carnival in September. In the fall, she had a huge December–running 31:15 for 10,000 meters at the Track Meet and 2:25:22 at The Marathon Project two weeks later. A stress fracture in the spring of 2021 derailed her chances to make the Olympic Team in the 10,000 meters, where she finished 12th on limited training. Healthy again in the fall, she finished sixth at the TCS NYC Marathon in 2:26:10.

Things changed in 2022 when Kellyn announced she was pregnant, eventually giving birth to a baby girl, Keagan, on December 28. Her return to racing in 2023 started in June when she ran the Portland Track Festival 5,000 meters and the Mastercard Mini 10k on back to back weekends. In July she won her second ever national title–taking top honors at the Bix 7/USATF 7-mile Championships. In November, she returned to the marathon for the first time in two years–finishing 8th at the TCS NYC Marathon in 2:29:48. At the 2024 U.S. Olympic Team Trials Marathon she finished 15th in 2:30:28.

A graduate of Wichita State University in Kansas, Kellyn was one of the school’s top distance runners of all-time. She finished third at the 2009 NCAA Indoor Track and Field Championships behind only stars Sarah Bowman (Tennessee) and Sally Kipyego (Texas Tech).
