2010 Chicago Marathon. Remember this race!?! 
The 2010 Chicago Marathon had an epic finish between Kenya Sammy Wanjiru and Ethiopian Tsegaye Kebede.

Six months later, the 24-year old Sammy would be dead. 

If you haven't seen it before, spend a few minutes and watch the finale. 

I'm reading Two Hours by Ed Caesar (book review coming soon) was reminded of this race. A section in the book explores the backstory of Sammy, which puts this race in a deeper perspective.
