Adversity is Certain

HOW YOU RESPOND DEFINES YOUR LEGACY

Ultra Runner

Trailblazing new distances for those like me. I was born with defects from face to my feet and never meant to walk. These defects include severe bilateral clubfoot, contracture disorders, knee and jaw deformities and more. My face and legs required extensive reconstructive surgeries.

I am the first hybrid prosthetic-orthotic user to complete an ultra marathon. The ultramarathon distances I finished are 31.1 miles (50km), 42.5 miles, 45 miles, 50 miles, 100k (62.14 miles), and 100 miles. As of 2026, no other person in my category has finished an ultramarathon. I will continue to trailblaze further distances. I am based in Las Vegas, NV with my incredible family (we got 3 amazing kids).

Recent Media Appearances

"Adaptive ultra runner Scott Davidson has achieved a milestone that stands alone in endurance sport: running 100 miles while wearing bilateral Exosym hybrid prosthetic-orthotics. The distance itself is one of the rarest accomplishments in athletics—even among healthy runners, only a tiny fraction ever reach 100 miles.

Many thousands of these devices are in use around the world, helping people with devastating lower-limb injuries and severe congenital limb defects regain basic mobility—including elite service members and accomplished athletes—yet no runner has completed any ultramarathon using them. For years, covering 100 miles under these conditions was widely viewed as impossible. Davidson’s finish rewrites that assumption, marking a singular milestone in endurance sport."

Running is the most difficult physical action for me to do, yet I love to run

I'm on a Vision Question to finish the Badwater 135 course in under 60 hours following the same rules implemented by the Bad Water 146 runners (see HERE). Each day I dream of Badwater - the World’s toughest ultra.

    At the 2026 Boston Marathon, Nike ran an ad, “Runners Welcome, Walkers Tolerated. I don’t respond to rage bait from brands. I prefer to move forward and focus on my goals. But this time I felt compelled to respond, because a giant pool of hard working para athletes got slapped…

  • 100 Miles Was Impossible, Until It Wasn’t

    March 22, 2026

    100 miles is unachievable for someone like me.  In fact, here are the odds: Clubfoot occurs in 1 in 1,000.¹ About 1 in 2 of those cases are bilateral clubfoot.¹ Roughly 1 in 3 to 1 in 2 bilateral cases are severe to very severe at presentation.¹ There are 148,169…

  • My Ultramarathon Timeline – An Exosym Ultra Runner’s Journey

    March 11, 2026

    February 11, 2022 My running hopes essentially ended in a mundane clinic in Everett, WA. The dynamic AFOs failed after many build attempts. The clinician didn’t care. “I’ll ship a new footplate when I get a chance but we’re really backed up. I’ll adjust the new set of AFOs and…

    My hope is that you will chase an impossible dream.  A dream that requires relentless work, ushers in sleepless nights, and overwhelms you with doubt.  A dream so big that you’re hypercautious to share with your community.  A dream that pushes you to reach your greatest potential. This is the…

    Dear parents of a school-age child, As your child returns to school, respectfully, I ask that you explain to your child that it’s never okay to make fun of classmates that have limb differences or other disabilities. Children with disabilities often live in uncertainty, need extensive treatments, and often lack…

You can adapt and thrive despite the adversity you face

Mission

Presumptively, my birth defects are due to my Veteran father’s Agent Orange exposures. Out of my adversities rose my purpose. Outside of running, I seek to:

1.  Educate and Legislate: notable percentage of the offspring of Veterans exposed to Agent Orange are born with defects. I am pushing the United States Government to change how they handle us. See my legislation HERE.

2. Bring high quality care: push for innovation and expanded access to life changing prosthetics and orthotics in order to eliminate the crippling barriers of limited mobility.

3. Empower: I spent a childhood bullied for the appearance of my face and legs. Older kids threatened to break my legs. Teachers and coaches made horrific comments. The stares and comments continue but I would never change how I was born. I made my adversities my purpose and I hope to empower others to do the same.

I will transcend my adversities in front of you as I trailblaze new distances for those like me

I live in constant uncertainty not knowing what next will fail on my body. I need expensive hybrid prosthetic-orthotics to stand and walk that are not covered by insurance. My entire life I've been told I can't. Yet I do. And through all this adversity, I am happy and full of purpose. In fact, my adversity is my purpose. You too can adapt and thrive despite the adversity you face.

 

Here you will find hope.
