Bone Marrow Registry at Door County Half Marathon

Be The Match, the largest national bone marrow registry, will offer FREE registration for individuals 18 – 44 during the Door County Half Marathon held Saturday, May 7 at Peninsula State Park.

The event will be held in memory of Bo Johnson, a Sister Bay boy who inspired the entire Door County community and beyond in his fight with leukemia in 2012. Though Bo died in September of 2012, his battle continues.  

“Every  four minutes someone like Bo is told they have a blood cancer or disease and the cure is someone else’s bone marrow or stem cells,” said Bo’s mother  Annika Johnson, who started the Go Bo Foundation. “Imagine a  cure for cancer!  It could be you!”

The GO BO Foundation brings hope to children with life-threatening medical conditions by funding research, supporting treatment, and helping their families during times of financial need.  

“Paying it Forward was Bo’s dream.” shares Annika “ I can’t imagine a better way than to share the gift of bone marrow to save another person’s life.”   

If you don’t qualify for the registry we encourage participation through donations.   To find out more about Be The Match or the GO BO Foundation go to or

“I have done a few half marathons around the midwest and this is by far the best. The organization and communication is fantastic and so are the facilities and race perks. The route is also ideal: starting flat, allowing for the body to acclimate ; followed by a steep incline and then down hill once the body gets a little fatigued. I love it!”
