Defending champions Tadese Tola of Ethiopia and Edith Masai of Kenya will join a strong field of world-class athletes in the 37th CIGNA Falmouth Road Race on Aug. 9. Tola will be challenged by two-time Falmouth runner-up and 2004 Olympic silver medalist, Meb Keflezighi, as well as several other elite runners from around the world as they race along Martha's Vineyard Sound from Woods Hole to Falmouth Heights."Tola defeated a very strong men's field last year to become Falmouth's first Ethiopian winner, while 41-year-old Masai put on a memorable show to defeat a strong group of much younger women," said John Carroll, the race's co-director and elite athlete coordinator. "This year we have another excellent field featuring some very talented athletes who would like to win Falmouth."Tola has had several impressive victories over the past year, including the 2008 New York City Half-Marathon and the Healthy Kidney 10k in Central Park, N.Y., with a course record 27:48.Keflezighi, of Mammoth Lakes, Calif., shadowed Tola for six miles before finishing in second place. It was the second straight year that Keflezighi was runner-up in Falmouth, and the best finish, along with his 2007 effort, by an American man since Ed Eyestone was second in 1990. On July 25, he won the U.S. 7-mile championship at the Bix road race in Davenport, Iowa.
