USA Track & Field Announces Full Rosters for World Athletics Road Running Championships Riga 23

Riga, Latvia, is about to witness an exciting gathering of some of the most talented milers, 5km runners, and half-marathoners in the United States at the inaugural World Athletics Road Running Championships, scheduled for October 1.

Leading the American contingent in Latvia is Sara Hall, a seasoned athlete with a strong presence in various distances in Riga. The 40-year-old Hall made headlines in 2022 when she set an American record in the half marathon with a remarkable time of 67:15 in Houston. This season, she continues to impress with a best time of 69:31. Joining her in the women’s half marathon are notable athletes such as Sarah Buchanan, who clocked her season-best time of 70:15 in Japan, Molly Grabill, who secured fourth place at the USATF Half Marathon Championships in Fort Worth, and Amber Zimmerman, the Philadelphia Marathon champion with a personal best of 70:55, set in Houston in January.

The mile race will feature 19-year-old Addy Wiley, a sophomore at Huntington University, and 1500m NACAC bronze medalist Helen Schlachtenhaufen. Wiley has been making waves recently, winning the women’s 1500 at the NACAC U23 Championships with an impressive time of 4:05.84 and clocking 3:59.17 to finish eighth at the Memorial Van Damme Diamond League meeting in Brussels. On the road, Wiley achieved a personal best of 4:31, securing third place at the USATF 1 Mile Road Championships. Schlachtenhaufen boasts an outdoor mile personal best of 4:27.09, achieved in June 2018, and a road mile personal best of 4:29.4, set during the 2018 Fifth Avenue Mile.

In the 5 km race, the dynamic duo of Weini Kelati and Fiona O’Keeffe will represent the United States. Both athletes have impressive 5km road personal bests, with Kelati’s standing at 15:04, earned when she finished second at the B.A.A. 5K in 2022, and O’Keeffe’s at 15:24, achieved in 2023. Kelati demonstrated her prowess by clocking 14:53.41 for fourth place at the Fast 5000 in Montesson, France, earlier this summer. O’Keeffe showcased her speed during the indoor season, recording a time of 15:01.34 at the Boston University Valentine Invitational.

The men’s half marathon will feature Jacob Thomson, this year’s USATF champion, who leads a formidable group. Thomson claimed the U.S. title with a personal best time of 62:38, narrowly defeating Leonard Korir by one second. Futsum Zienaselassie, another strong contender, took third place in that race with a time of 62:39. Zienaselassie boasts an impressive personal best of 61:21 and secured the USATF 10-mile title in 2019. He also achieved ninth place at the Rotterdam Marathon in April, clocking a personal best time of 2:09:40. Abbabiya Simbassa, the fourth member of the U.S. quartet, placed fourth at the USATF Championships and holds the fastest personal best at 60:37, which he set last year in Valencia, Spain. Simbassa also won the USATF seven-mile title in July and set a marathon personal best of 2:10:34 in Prague in May. Reed Fischer, the winner of the Chicago half marathon in June, rounds out the team with a personal best of 61:37, achieved in 2020, and a season best of 61:51.

The mile race on the men’s side features two exceptional athletes, Sam Prakel and Hobbs Kessler. Prakel, a two-time USATF road mile national champion, has had a successful track record, finishing fourth in the 1500 at the Toyota USATF Championships and setting a personal best time of 3:34.63 in June. He also won the USATF Indoor Championships 3000 in Albuquerque in February and holds a career best of 3:48 in the road mile. Kessler, a 20-year-old rising star, has claimed victory in a pair of road miles this season and achieved a personal best time of 3:32.61 in the 1500 at the USATF LA GP in May. In 2021, Kessler set a U.S. U20 record in the 1500 with a time of 3:34.36.

Olin Hacker, the reigning NCAA 5000 champion, brings his talent to the road with a track best of 13:09.94 and a solid road 5k time of 13:27 in 2023. He secured third place in the 3000 at the USATF Indoor Championships and finished seventh in the 5000 at the Toyota USATF Outdoor Championships. Ahmed Muhumed, who crossed the finish line right behind Hacker at the BAA 5k with the same time of 13:27, will also compete in the 5 km race. Muhumed achieved eighth place in the 5000 at the Toyota USATF Outdoor Championships.
