Autumn represents the peak of the global marathon calendar. Many of the world’s largest and fastest races take place between September and November, attracting deep international fields and runners targeting end-of-season personal bests after summer training blocks. As a result, the autumn period consistently produces some of the largest concentrations of sub-3 performances anywhere in the world.

The scale of participation plays a major role in shaping the rankings. Several of the world’s biggest marathons take place during this window, generating enormous volumes of sub-3 performances simply through field size. At the same time, a number of smaller races produce unusually high sub-3 proportions where the field is strongly weighted toward experienced runners chasing fast times.

The Chicago Marathon leads the autumn rankings by combining scale with elite speed. In 2025 the race produced 4,054 sub-3 finishers from 54,284 runners (7.5%), supported by a 2:02:23 winning time. Other major international races also make significant contributions to global sub-3 totals. Berlin Marathon produced 2,382 sub-3 performances from 48,028 runners, although unseasonably warm conditions reduced the proportion of fast times compared with typical years. Meanwhile the New York City Marathon generated 2,395 sub-3 finishers despite the more demanding course profile.

One result stands out for a different reason. The Abingdon Marathon recorded an exceptional 17.0% sub-3 rate, with 173 sub-3 finishers from just 1,016 runners. This unusually high density was largely driven by the inclusion of an England vs Wales Masters representative marathon, which concentrated a large number of competitive runners into a relatively small field. While the circumstances were unusual, the result illustrates how strongly field composition can influence sub-3 outcomes.

Taken together, the autumn - or fall - rankings highlight a season defined by both scale and depth. From major global marathons producing thousands of sub-3 performances to smaller races with highly concentrated competitive fields, this period remains the most significant segment of the marathon calendar for runners targeting the three-hour barrier.

About These Rankings

These rankings present a cut of the Sub-3 World Marathon Rankings, drawing on verified results from marathons held between September and November 2025. Each race is scored using Sub-3’s 45:45:10 model, which weights the proportion of sub-3 finishers, the total number of sub-3 performances, and the fastest winning time. Together, these measures allow for consistent comparison across events of very different sizes and profiles.
