Sean “Professor Marathon” Hartnett’s chronicles of 9 recent Chicago Marathons, 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, he somehow finds time to teach geography at Wisconsin–Eau Claire, serve as the Founding Director of the Confluence Center For Chippewa River Studies and act 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 ?)
