Making Our Mark on Colon Cancer is a team built from the strength of family and friends who come together each year to honor Mark Velbeck and to fight for a future with earlier detection, better treatment, and more survivors.

We run, walk, and fundraise because colon cancer changed our lives and because we believe in making a difference for the families who will face it next. With every mile and every dollar raised, we’re making our MARK on colon cancer and carrying Mark’s legacy forward with purpose and love.
