9. West Springfield's 2014 3-peat DMR
The team of Katie Kennedy, Michelle Lipka/Kiera Bothwell, Reagan Bustamante, and Caroline Alcorta was legendary. Their dominance in the DMR might not ever be matched by any team in the nation for quite some time. They not only won major DMR titles, they swept them going three for three in major competitions.
That included winning both the indoor and outdoor national titles with a big invitational title in between. Their ultimate time of 11:39 is one of the fastest ever run in that event.
