Two-time defending champ Florence Kiplagat
is back in Chicago but she's an underdog as Tirunesh Dibaba
, arguably the greatest women's distance runner in history, is racing. If they falter, American Jordan Hasay
could win but having looked at the stats, we're worried she may never run faster than her debut in Boston.
*MB: Will Jordan Hasay ever run faster than her 2:23:00 debut in Boston? Yes or no.
