The marathon detective

Last weekend, the Kenyan runners Geoffrey Kirui and Edna Kiplagat won the men's and women's races at the 121st Boston Marathon. 

But as recent high-profile cases show, not every athlete is prepared to race within the rules.

Some amateur runners are also resorting to cheating to record a qualifying time and score a prized spot on some of the world's most prestigious races. 

Not if Derek Murphy of Marathon Investigation can help it, though. He's a runner and business analyst who's also become a part-time, amateur marathon sleuth as a hobby, using technology to uncover hundreds of suspect times and cheating runners.
