The third annual Brain Tumor 5K's twenty-one hundred participants, including former Washington Redskin Mark Rypien, were joined by many families who had loved ones affected by brain tumors. The event, which was organized by The Brain Tumor Society, a national non-profit organization committed to finding a cure through research and education, raised $230,000 for the cause. Brain tumors are the second leading cause of cancer deaths in children and young adults, and one of the fastest growing causes of cancer in the elderly.

As the runners left the start line in West Potomac Park, Matt Cooke, Washington DC, Philippe Kozub, Bethesda, MD, and Alden Hall, Washington, DC, charged to the front. Kozub challenged Cooke for the lead several times, but Cooke managed to pull away for the win in 16:10. Kozub held on for second (16:27) and Hall for third (16:42). Ronald Shaiko, 40, of McLean, VA, finished fourth in 16:51, and was the first finisher in the masters division. Brad Mele, 14, of Gaitherburg, MD, finished in 18:27.

In the women's race, Desiree Ficker, Potomac, MD, took the lead from the start and was never challenged, finishing in 18:28. Her closest competitor, Gloria Santarpia, Odenton, MD, finished in 18:46. Win Rincon, 40, of Alexandria, VA, finished third in 19:36 and was the first female masters division finisher.

Many participants walked the course in memory of their loved ones and to support the cause.

The kids participated in a quarter-mile fun run after the start of the 5K and each received a medal. All participants enjoyed post-race refreshments including Ben & Jerry's awesome ice cream.
