Marblehead’s Shalane Flanagan competes in the women’s marathon on Sunday, Aug. 5. The race will be shown live on NBC, Channel 7, from 6 a.m. to 9 a.m.

Her Marblehead High School accomplishments included three-time All-State cross country performances, a first-place All-State finish in the mile, and a two-mile win whose record still stands; her 4:46 mile won the Indoor National Scholastic Championships.

She attended the University of North Carolina-Chapel Hill, where she won national cross country titles in 2002 and 2003 — becoming the first individual champion in the sport in Tar Heel history — and numerous track accolades.

On August 16, 2008, Flanagan finished 3rd in the 2008 Olympic Womens 10000m Finals in Beijing, capturing the Bronze medal. She also set a new American record in 30:22.22, shattering her own American record set earlier in the year. She is only the second American woman to receive an Olympic medal in the 10,000 m.
