Emily Sisson separated herself from the competition early, and became a repeat winner in the Reebok Boston 10K for Women Monday afternoon.
The 26-year-old from Rhode Island pulled away from Buze Diriba of Ethiopia at the 3-mile mark and held on to her lead down the stretch to claim victory in 30:39 — a comfortable 33 seconds ahead of the second-place Diriba.
Erin Clark of Arizona (32:19), Dylan Hassett of Rhode Island (32:28), and Holly Rees of the United Kingdom (32:46) rounded out the top five finishers in the open division.
Sisson, who was making her third appearance in the former Tufts 10K, became the first repeat winner since Molly Huddle in 2015. Huddle won the event four times, including three straight from 2008-10.
Formerly known as the Tufts Health Plan 10K for Women, the race is the largest all-woman running event in New England and has been a Columbus Day staple in Boston since 1977. Running through the Back Bay and into Cambridge, competitors make their way along the Charles River before finishing on Charles Street between the Public Garden and Boston Common.
