Run Ottawa is proud to welcome elite Kenyan marathoner and 2023 New York City Marathon champion Albert Korir to the start line of the 2025 Tartan Ottawa International Marathon, taking place on May 25 during Tamarack Ottawa Race Weekend 2025.

Korir, who captured victory in the 2019 edition of the Ottawa marathon with a time of 2:08:03, will return to Canada’s capital with his sights set on reclaiming the title and building on a career defined by consistency and championship excellence.

Since his win in Ottawa, Korir has cemented his reputation as one of the top marathoners in the world. Later in 2019, he finished second at the New York City Marathon (2:08:36), and in 2021, he returned to win it (2:08:22), claiming his first World Marathon Major title. He has continued to perform at the highest level, finishing second in New York again in 2023, where he ran a personal best of 2:06:57. Korir has also delivered strong results in Boston, placing among the top six three times, including a fourth-place finish in 2023 (2:08:01).

Known as one of the best championship racers of his generation, Korir brings global experience and proven performance to this year’s elite field, which is shaping up to be one of the most competitive in the event’s 50 year history. His return adds further excitement to what is already expected to be a thrilling race through the streets of the national capital region.

Although the Tartan Ottawa International Marathon is officially sold out, spectators are encouraged to line the course and cheer on this world-class field, or subscribe to the Run Ottawa YouTube channel to catch the Tartan Ottawa International Marathon live from Canada’s capital. With this year’s elite field shaping up to be one to watch, you won’t want to miss a moment!
