Tigist Assefa Berlin Marathon Course Record Race Map

AT THE 2022 Berlin Marathon, Ethiopia’s Tigist Assefa dropped the course record for the venerable German race to 2:15:37.

Click the image below to view “Professor Marathon” Sean Hartnett’s map of Assefa’s Ethiopian record run. Will she go faster as she defends her title in 2023 (Sunday, September 24)?

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 ?)
