Kenyan Hellen Obiri will pursue a third straight Boston Marathon title in April, the Boston Athletic Association said on Wednesday, while Ethiopian Sisay Lemma will defend his title in a speedy men's field.

Hellen Obiri will compete in her third Boston Marathon in April, looking to make it three wins from three. She has pocketed millions from her marathon career.
