ISTANBUL, November 2, 2025 — Kenya’s Rhonzas Kilimo and Ethiopia’s Bizuager Aderra claimed sensational victories at the 47th Türkiye İş Bankası Istanbul Marathon, both securing the biggest wins of their careers and pocketing $50,000 each.

In warm, sunny conditions, 29-year-old Kilimo edged out defending champion Dejene Debela in a fierce uphill battle to the finish, clocking 2:10:12. Debela was just 11 seconds back in 2:10:23, with fellow Ethiopian Sufaro Woliyi third in 2:10:26.

The women’s race delivered the closest finish in the marathon’s history. 22-year-old Bizuager Aderraemerged as a surprise champion, breaking her personal best with 2:26:19 — just two seconds ahead of Olympic steeplechase silver medalist Sofia Assefa. Kenya’s Joan Kilimo, unrelated to the men’s winner, finished third in 2:26:36.

More than 6,000 runners competed in the marathon, with a total of 42,000 participants across all distances. The event holds a World Athletics Gold Label and is Turkey’s premier marathon.

Men’s Race: Kilimo Conquers the Hills

The men’s race began at an even pace, with the lead pack — including 16 athletes and four pacemakers — passing 10K in 30:41 and halfway in 1:04:41. Hopes of breaking the six-year-old course record (2:09:44 by Daniel Kibet) faded as the tempo dropped in the second half under 20°C heat.

As the runners approached the final mile-long climb, five men remained: Kilimo, Debela, Woliyi, Kenya’s Isaac Too, and Turkey’s Hüseyin Can. Too and Woliyi began to fade, leaving Kilimo and Debela to duel for victory.

“I had no clue about the uphill section at the end — it was a surprise to me,” Kilimo said afterward. “But I train in hilly areas around Iten, so I was ready.”

Kilimo, who ran a personal best of 2:06:09 in Seoul in 2024, crossed the line first in 2:10:12. “This was my biggest win so far,” he added. “My next goal is to run 2:03 on a fast course.”

Can delighted the home crowd by finishing fifth in a personal best of 2:10:58.

Women’s Race: Aderra’s Last-Minute Surge

The women’s field set an ambitious early pace — 33:38 at 10K and 1:11:22 at halfway — led by a pack of five: Ethiopians Bizuager Aderra, Sofia Assefa, Tigst Getnet, Gete Dukale, and Kenya’s Joan Kilimo.

As the temperature rose, the pace slowed. Assefa briefly fell behind but fought back, and with one kilometer to go, four women were still in contention. Assefa appeared to edge ahead, but Aderra responded with a decisive surge over the final 400 meters, sprinting into Sultan Ahmet Park to secure the win.

“This is the biggest win of my life — and a personal best,” said Aderra, whose previous mark was 2:28:27 from Rabat earlier this year. “My next goal is to go under 2:20.”
