The 2026 Chicago Marathon concluded with a historic Adidas sweep, as winners Amos Kipruto and Hawi Feysa set course records in the unreleased Adizero Adios Pro Evo 3. In stark contrast to the celebration in Chicago, the running community mourned the tragic death of a KAIST graduate student during the Seoul Race, sparking urgent discussions on race safety protocols. Meanwhile, New Balance and ASICS are expanding their community-driven "run club" models in Tokyo and Chennai respectively, signaling a shift toward localized engagement over pure sales.

Adidas Dominates Chicago with Record-Breaking "Evo" Shoes
The 2026 Bank of America Chicago Marathon, held on October 11, saw Amos Kipruto (men’s) and Hawi Feysa (women’s) win in 2:01:09 and 2:13:33 respectively, both wearing the Adidas Adizero Adios Pro Evo 3. This victory marks a significant moment for Adidas, which swept the podiums, while Nike’s unreleased "Apex" prototype took third place. The dominance of the Adios Pro Evo 3 reinforces the current trend of ultra-lightweight, high-stack carbon-plated shoes defining elite performance.

Tragedy at Seoul Race Highlights Safety Gaps
A 20-something female runner, identified as a KAIST graduate student and running influencer named Yoo Ji-won, died after collapsing near the finish line of the 2026 Seoul Race on October 12. She had reportedly led the women’s half-marathon division before collapsing approximately 500m from the finish. The incident has triggered widespread mourning and debate in Korean media about medical support and heat/acclimatization protocols for amateur runners in major urban races.

New Balance Launches "Tokyo Legacy Half Marathon EXPO" Experience
New Balance Japan announced on October 13 that its booth at the upcoming Tokyo Legacy Half Marathon EXPO (October 17-18) will feature special talk shows with newly contracted athletes, a "Shakeout Run," and an after-party. This move reflects the brand's strategy to integrate deeply into the pre-race culture of major Japanese events, moving beyond traditional product displays to create community hubs for runners.

ASICS Expands Run Club Model in India
ASICS has announced a partnership with the Freshworks Chennai Marathon 2027 and launched the "ASICS Running Club" in India. This initiative aims to support runners through structured training and community engagement, mirroring the global "run club" boom where brands act as lifestyle partners rather than just equipment providers.
Local view
Japan: Media coverage focuses heavily on the cultural integration of running brands. Running Street 365 highlighted New Balance's comprehensive EXPO lineup, noting that events like the Tokyo Legacy Half are becoming festivals that blend race preparation with social experiences. The narrative emphasizes that for Japanese citizen runners, the "EXPO" is as critical as the race itself for gear selection and community bonding.
South Korea: The local press is dominated by the aftermath of the Seoul Race fatality. Outlets like Sisa Journal and Maeil Business Newspaper are reporting on the wave of online condolences and the scrutiny facing race organizers. The term "running fever" (running boom) is being used to contextualize the tragedy, with experts warning that the rapid increase in amateur participants may be outpacing the safety infrastructure of some large-scale city races.
