Killian Korth

Kilian Korth is an ultramarathon and trail runner known for his performances in 200-mile and longer trail races. He became one of the leading athletes in the 200-mile discipline after winning the Triple Crown of 200s in 2025 and winning the men's race at the Cocodona 250 in 2026.

Running career

Korth began appearing in ultramarathon results in the late 2010s, including finishes at the 2018 Cactus Rose 100 Mile, the 2019 Leadville Trail 100 Run, and the 2021 Ouray 100 Mile Endurance Run, where he placed third overall.

In 2022, Korth won the DC Peaks 50 in Kaysville, Utah. Destination Trail reported that his cumulative time broke Michael McKnight's 2019 Triple Crown record by about seven and a half hours.

In May 2026, Korth returned to the Cocodona 250 and finished second overall and first among men. iRunFar reported his time as a new men's course record and the second-fastest time ever run at the race.

200-mile racing and Triple Crown of 200s

The Triple Crown of 200s consists of the Tahoe 200, Bigfoot 200 and Moab 240, three long-distance trail ultramarathons held in the western United States. Korth won all three races in 2025, finishing the Tahoe 200 in 52:40:52, the Bigfoot 200 in 45:03:41, and the Moab 240 in 58:45:47.

His Triple Crown performance was covered by Canadian Running, BroBible, Destination Trail, the American Trail Running Association, and endurance-running podcasts focused on the rise of 200-mile racing.

Cocodona 250

Korth has raced the Cocodona 250 multiple times. He recorded early unfinished attempts at the race in 2022 and 2024, and finished 11th overall in 2023.

In 2026, Korth won the men's race and placed second overall behind Rachel Entrekin, who became the first woman to win Cocodona outright. His finish was covered by iRunFar, Runner's World, Outside, Canadian Running, Marathon Handbook, The Guardian, The Washington Post, and El País within broader coverage of the race.

Runner's World later described both Entrekin and Korth as examples of breakthrough performances at Cocodona, quoting Entrekin's view that both athletes "managed to stick the landing" after earlier doubts or setbacks at the race.

Media coverage

Korth has been covered primarily in endurance-running media, race reports, and podcasts focused on the growth of 200-mile racing. His 2025 Triple Crown season was covered by Destination Trail, Canadian Running, BroBible, the American Trail Running Association, Singletrack, Everyday Ultra and Cameron Hanes's podcast.

His 2026 Cocodona performance received coverage from iRunFar, Runner's World, Outside, Canadian Running, Marathon Handbook, The Guardian, The Washington Post, El País, and Singletrack. In race previews, Marathon Handbook identified Korth as one of the major men's contenders, citing his recent success in 200-mile races.
