The Gay Head 10K is unique among the many Island road races, first by distance, and also because of the backdrop in the homestretch, as the winning runner passes the famed Gay Head Lighthouse on the way around Aquinnah Circle to the finish line.

On a cloudy, windy Sunday morning, Rene Da Silva of Vineyard Haven claimed his second win in the sixth annual event, which benefits the Save the Gay Head Light Committee, leading 148 runners to the finish in 38:46.21.

Ryan Sawyer of Edgartown ran second in 39:50.78, more than two minutes in front of third-place Vlad Trifanica of Sibiu, Romania, who clocked in at 41:52.65. From there, the runners were more tightly packed. Westford’s Marc Cajolet and Chris Cajolet of West Tisbury finished in a dead heat for fourth and fifth, with times of 42:20.28 and 42:20.37. Levi Lilienthal of South Portland, Maine (42:39.53), Peter Septoff of Cambridge (43:23.27), and Andrew La Manna of New York City (43:30.34) took spots six through eight.

Mary Clabby of Marietta, Ga., was the women’s winner, and ran ninth overall in 43:59.08. Alex Testa of Reading, the fastest woman in the 2015 race, closed out the top 10 with a time of 44:08.38.
