AS THE 2023 EDITION of the Chicago Marathon draws near (Sunday, October 08), the links below should enrich your enjoyment of the men’s and women’s comps on a comparative basis: ”Professor Marathon” and geographer Sean Hartnett’s highly detailed maps of the Chicago course records — Brigid Kosgei’s 2:14:04, now No. 2 all-time for women, and Dennis Kimetto’s 2:03:45 men’s mark from 2013. You’ll also find links to the two World Record maps below.
Hartnett has this to say ahead of Chicago 2023: “A Sunday morning dew point temp of 4C (40F) has me thinking records. Both Chicago course records should be in play – and even after Berlin or perhaps inspired by Berlin, the World Records may be challenged.”
