Robert Cheruiyot is racing to win his fourth title in the Boston Marathon. He has already won it three previous consecutive times and is looking to take this race for a record fourth time.
He faces competition from fellow compatriots–James Kwambai returns, as does Chicago champion Patrick Ivuti. Both men are training partners of Cheruiyot. This is definitely a race to watch.
