Kenyans cleanup in Boston

American CJ Albertson set an aggressive early pace to lead the men's field by two minutes and 13 seconds through the first half but saw his headstart disintegrate over hilly terrain after the 20-mile mark, as a tight pack overtook him.

Kipruto, who won the Prague Marathon in May, pulled away with less than 10 kilometres to go and had secured a commanding 41-second lead heading into the last mile, absorbing the cheers along Boylston Street as he broke the tape in two hours, nine minutes and 51 seconds.
