Ahead of the Chicago Marathon on Sunday (October 9) Sean “Professor Marathon” Hartnett’s chronicles of 10 recent editions of the race, a mix of meticulously annotated maps and slideshows of the races. All in all, a deep dive into the Windy City’s oft-eventful 26-miler.

When “Professor Marathon” isn’t crafting topographical maps and pace charts for 26-milers around the world, the now Emeritus geographer at Wisconsin–Eau Claire, serves as the Chair of the Lower Chippewa River conservation organization and hits the airwaves Thursday afternoons as a DJ on a community radio program called “All Things 6 String.” (Hint: Sean's the one in the photo who never set a World Record ?)
