AIMING FOR TOP FINISH: Patrick Makau departs for Boston, faces another marathon test

Patrick Makau from Kenya celebrates as he wins the Frankfurt Marathon race in Frankfurt, central Germany, Sunday Oct. 28, 2012. Patrick Makau won the Frankfurt marathon in cold and sunny conditions but failed to break his world record on Sunday.

Former World Marathon Record holder Patrick Makau will face his biggest challenge so far, when he lines up on Monday along the Boston Marathon streets.

Despite leading the elite field owing to his fast 2:03.38 personal best time, Makau is uncertain if his body will endure the quick course through Boston streets, as he debuts in the USA soil over the 42km distance on Monday.
