Honoring the courage and strength of our community

Marcy Speer was a dedicated wife, mother, and world-renowned geneticist at Duke University. She lost her battle with cancer in 2006. At the time, Marcy’s Run was created as a way to honor her memory as well as her contributions to the TDS community, and to support science education. Sadly, in the years since the race began, the TDS community has had many other families affected by cancer. With the blessing of the Speer Family, the race took on a new name several years ago.

The Twister Trot honors all families who have been, or currently are being, affected by this terrible disease, and we invite all of our racers to honor a friend or family member impacted by cancer at our race.
