Why We Move: About ALD & Our Mission


• What is ALD? Adrenoleukodystrophy (ALD) is a progressive, rare genetic disease that affects about 1 in 15,000 people worldwide. It progressively damages the adrenal glands, spinal cord, and myelin of the nervous system. It most severely affects boys, some of whom suffer severe neurological symptoms that can result in death if the disease is undiagnosed and not treated very early.

• Our "Why" : This event is inspired by the vision of our son, Nicholas, who underwent a successful bone marrow transplant to halt the progression of his cerebral ALD at the University of Minnesota Children's Hospital (a world leader in ALD treatment).

100% of the funds raised from this event go directly to the University of Minnesota Leukodystrophy Center for ALD Research. Your support funds early identification, more effective therapies, treatment options, and hopefully, one day, a cure.

Support the Cause (Beyond Registration) - The majority of our impact comes from donations above and beyond race registrations. If you cannot participate, or if you want to make an even bigger difference, please consider supporting us in one of these ways:

  1. Add a donation: You can add a donation directly during registration.
  2. Direct Donation: Use the "Donate" tab on this page to give without registering.
  3. Donate by Check: To help us avoid online processing fees, you can mail a check directly to:
    Knockout ALD
    1551 Timberlake Manor Parkway
    Chesterfield, MO 63017

THANK YOU for helping us champion this cause for a decade. Let's Knockout ALD together!
