Marathon Season 2026: Mid-Year Performance Roundup

Halfway through 2026, the global marathon circuit has already produced some of the most remarkable performances of the decade. Favorable weather conditions, next-generation shoes, and a depth of talent not seen since 2019: marathon is going through a record-performance phase. Here's what the first six months of the season have told us.

The Women's World Record Fell

The major event of the spring season came from Rotterdam in April 2026. Tigist Assefa (Ethiopia) set a new women's marathon world record at 2:09:56, breaking Brigid Kosgei's 2:14:04 (Chicago 2019) in spectacular fashion. It's the first time a woman has broken the 2:10 barrier in a certified marathon. The progression of women's marathon performance over the past five years is unprecedented in the event's history.

Men's Field: Alexander Mutiso and Kenyan Depth

The fastest men's marathon of 2026 belongs to Alexander Mutiso (Kenya): 2:03:28 at Rotterdam. That's the fastest time of the year and 12th-fastest all-time. Eliud Kipchoge is absent from the spring 2026 season — a minor injury forced the Olympic champion to postpone his next race to the Berlin Marathon in September.

Kenyan depth remains extraordinary, but the Ethiopian scene is clearly building on both the men's and women's sides.

US Depth: The Story of the Season

Five American men ran sub-2:08 in the spring 2026 season — a historic record for a single season. The rise of American distance athletics, fueled by college programs and an active road racing circuit, is starting to translate into world elite performances.

At the 2026 Boston Marathon, three Americans finished in the top 10 men — a phenomenon not seen since the 1980s.

Fall Majors: The Next Opportunity

Berlin (September 28), Chicago (October 11), New York (November 2): the second half of the 2026 season is shaping up to be exceptional. Kipchoge will be in Berlin. Assefa is announced for Chicago. The global marathon community waits to see if the spring records can be pushed even further in optimal fall conditions.
