Blood cells produced in human bone marrow can save the life of someone with leukemia, but only if the donor and patient are carefully matched. Jeana Moore is walking the length and breadth of the United States to round up more donors, and boost the odds that those matches can be made.

In addition to her one-to-one conversations, Jeana Moore is also actively working to set in motion plans for bone marrow drives in many of the communities she’s passing through.

She notes that they combine well with blood drives that may already be scheduled. Moore’s journey is also inspiring “sister” bone marrow drives in communities far from her pedestrian route.

Moore is just 900 miles—and four pairs of shoes—into her trek, but already she considers it an unqualified success.

To follow her progress, you can read Jeana's journal of her journey and see her planned itinerary, which are both featured on her website. Or go directly to  the National Bone Marrow donor registry to sign up or get more information.
