Doris Lemngole Turns Professional With On

Doris Lemngole has turned professional with On, six days after the best race she has ever run. The Swiss brand confirmed it Thursday, promoting the 24-year-old Kenyan from the NIL deal she signed in August 2025. On Sept. 4 she finished second in the 3,000m steeplechase at the Diamond League final in Brussels in 8:52.86, a time only five women have beaten.

Winfred Yavi had run at the front for most of it and was caught in the home straight by both Kenyans, Faith Cherotich winning in a meeting record of 8:51.61 with Yavi third. Yavi is the Olympic champion, and until Brussels she had beaten Lemngole every time they met this year. Her Paris gold-medal run was 8:52.76, a tenth quicker than Lemngole’s Brussels time. Above her on the all-time list sit Beatrice Chepkoech’s world record of 8:44.32, then Yavi, Peruth Chemutai, Cherotich and Ruth Jebet, whose 8:52.78 she missed by 0.08 seconds.

Cherotich is the reason none of this is simple. Lemngole has never beaten her, not in four meetings this season and not in Tokyo last September, where Cherotich took the world title and Lemngole was fifth, just under 11 seconds back. What has changed is the size of it. Cherotich had six seconds on her at the Prefontaine Classic on July 4 and five in Lausanne on Aug. 21. Six days later in Zurich it was 0.12, and in Brussels 1.25. Under the Beijing entry rules, Kenya gets three places in 2027, four if one athlete holds a wild card, and Cherotich’s world title should earn hers. Lemngole is among a deep Kenyan field for the rest.

“Watching her dominate the collegiate ranks, rewrite record books, and immediately challenge the best in the world at the Diamond League and World Championships made it a natural decision to offer Doris a professional contract,” said Niklas Buehner, head of athletics at On.

The Record She Has Already Beaten Three Times

The collegiate record she leaves is 8:58.15, from the NCAA final in Eugene on June 14, 2025. It made her the first collegian under nine minutes and took almost 12 seconds off the mark she set herself earlier that season. It is also, now, only the fourth-quickest steeplechase of her life. She has gone under it three times since leaving college, all inside nine weeks this summer, once there was nobody left to race but professionals.

Alabama got five NCAA titles out of her in three years: two steeplechase, two cross country, one indoor 5,000m. In December she became the first Alabama athlete to win The Bowerman. Her 18:25.4 over 6K at Gans Creek last November was the quickest anyone has won that race by roughly half a minute, LetsRun noted, and put 13.5 seconds into Jane Hedengren.

Alabama’s roster still lists her as a junior for 2025-26, and neither On nor the university has said whether a fourth season was open. A third straight cross country title would have been worth staying for: only Sally Kipyego has won three, at Texas Tech from 2006 to 2008, and she was Kenyan too. Lemngole’s last race in an Alabama vest was a win that lasted about an hour. She crossed first in the 5,000m at the 2026 NCAA outdoor championships in 15:11.71, then lost the title for taking too many steps inside the line. New Mexico’s Marion Jepngetich was handed the win.

On Has Made This Move Before

In June 2024 On converted Olivia Markezich, Maia Ramsden and Ky Robinson from NIL deals into professional contracts, all three joining its OAC Global group in Boulder under Dathan Ritzenhein. In May it launched a sprint team in Los Angeles anchored by Ghanaian Olympian Benjamin Azamati, with the NCAA 100m champion Samirah Moody among its founding four. Thursday’s release says only that she joins “On’s global roster of professional athletes.” It does not say which group, which coach, which country, or for how long.

“Now, to officially turn professional with On feels like the start of a new chapter in a journey that has already meant so much to me,” Lemngole said in the release.

Budapest, where the World Athletics Ultimate Championship opens Friday, has no steeplechase among its 28 events. The next global title in hers is Beijing, Sept. 11 to 19, 2027.
