Toronto, Canada — October 19, 2025. The stage is set for another East African showdown at the TCS Toronto Waterfront Marathon, a World Athletics Elite Label Race. Two top Kenyan runners, Beatrice Cheserek and Cynthia Chemweno, have been confirmed to take on Ethiopia’s rising stars Almaz Kebebe and Adane Anmaw, in what promises to be one of the most competitive women’s races in the event’s history.

Beatrice Cheserek’s Confident Marathon Debut

At 26, Beatrice Cheserek will make her marathon debut in Toronto, bringing impressive credentials to the start line. She owns a half marathon personal best of 1:06:48, recorded while winning the 2022 Cardiff Half Marathon, and has already experienced the pressure of major marathons.

In 2023, she paced compatriot Rosemary Wanjiru through 30 kilometers of the Tokyo Marathon, a World Marathon Major that Wanjiru went on to win in 2:16:28. Cheserek’s performance that day proved her strength over the distance — and she’s ready to test herself as a full competitor.

“This is my first marathon, and I hope to do my best,” Cheserek said. “I paced in Tokyo for Rosemary Wanjiru, and she ran 2:16, so I know I am strong. I want to run 2:20 or 2:19 in Toronto. It’s a fast course.”

After taking maternity leave to give birth to her son Fabian Kiprop, now 15 months old, Cheserek has made a steady comeback. Earlier this year, she placed sixth at Spain’s Santa Pola Half Marathon, running 1:10:25. Her confidence has grown with each training cycle.

“My training now is going well,” she added. “Last week I did 40 kilometers and finished strong. I know Toronto is not a hard course — a little bit faster — and I’m ready.”

 Cynthia Chemweno Targets Another Breakthrough

 Her teammate Cynthia Chemweno, 28, also arrives in Toronto with growing momentum. In her marathon debut at Hamburg in April, she finished fifth in 2:23:39, a time that gave her valuable confidence heading into the fall season.

“Hamburg was my first marathon, and I managed a good time,” Chemweno said. “The course was great, and I really enjoyed it. I’m excited to improve in Toronto.”

Chemweno and Cheserek are both part of the ASICS Mezzo Sports Management group. The two trained together frequently before Chemweno relocated to Chojo Camp in Kaptagat — a name derived from the Japanese word meaning “striving for the peak.” The camp is home to several top Kenyan male athletes and coaches. 

Cheserek continues to train from her hometown of Chepkorio, 40 kilometers from Iten, supported by her husband Cyrus Kiplagat, himself a competitive runner.

“He is the one who helps me with pacing,” she explained. “When I train, my sister-in-law looks after Fabian. It’s not always easy, especially during the rainy season when the dirt roads are impassable, but I keep working hard.”

Course Record in Sight

The Toronto Waterfront Marathon course record of 2:20:44, set by Ethiopia’s Waganesh Mekasha, could be under threat. Mekasha is a training partner of Kebebe and Anmaw — both part of the emerging Ethiopian generation now challenging Kenyan dominance.

With Cheserek targeting a 2:19 and Chemweno already proven in the 2:23 range, organizers and fans alike are anticipating a fast, tactical race through downtown Toronto.

Final Thoughts

The 2025 TCS Toronto Waterfront Marathon is shaping up as a clash of ambition, resilience, and national pride. Both Kenya and Ethiopia will field athletes capable of rewriting the record books on one of North America’s premier marathon stages.

Whether it’s Cheserek’s inspired debut or Chemweno’s drive to improve on her Hamburg performance, Toronto could once again deliver the kind of breakthrough that defines a career — and keeps East Africa at the center of the global marathon conversation.
