Chicago Marathon 2025: Conner Mantz’s American Record & The Rise of Jacob Kiplimo | Instant Reaction

In this instant reaction episode of the Marathon Handbook Podcast, Michael, Alex Cyr, and Katelyn Tocci recap all the action from the 2025 Chicago Marathon (00:00). Alex argues that Kelvin Kiptum’s 2023 world record looms even larger after this year’s results (02:40), while Katelyn spotlights Jacob Kiplimo’s blistering yet flawed attempt at history (05:15). The team dissects the record-breaking American run from Conner Mantz (13:50) and what it means for U.S. distance running (19:30). On the women’s side, Hawi Feysa’s near “immaculate” marathon earns praise for its perfect pacing (24:40), and the crew debates the future of American women’s marathoning (31:30). Plus, deep dives into the super shoe wars—Nike, Adidas, Hoka, and ASICS—and what’s next on the marathon circuit heading into Toronto (45:30).
