My Ultramarathon Timeline – An Exosym Ultra Runner’s Journey

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 send them later.” I nodded, and replied “thank you, good seeing you” and threw on my backpack and walked out the door. I flew home, but now poorer, depressed, and looking up wheelchair options.

February 12-13, 2022
I started searching for anything that might work. One name kept appearing: the Exosym.

I devoured blogs, social media threads, and YouTube videos late into the night. Hope started growing again—dangerously big. Big enough that I caught myself imagining an ultramarathon. Which was absurd. I could barely walk.

February 14, 2022
I called the Hanger Clinic in Gig Harbor, WA and asked for a consultation with IDEO/Exosym inventor Ryan Blanck

February 17, 2022
A phone consultation with Ryan Blanck took place. Then came the waiting.

February 18, 2022
Koreen Peterson informs me the clinic had a cancellation for next week. They could squeeze me in. I booked a flight, car, and hotel.

February 22, 2022
I travel from Vegas to Gig Harbor, WA and hard launch my Exosym journey.

Stop timeline…
Note, a lot happens between these dates above and that below. I experienced many setbacks from February 22, 2022 and onwards as I grew into my new running life. This is the nature of prosthetics and orthotics and I am no different. Progress was never linear. I relied heavily on Ryan Blanck and others to help build me into a runner.

Resume timeline…

3 days into wearing the Exosyms I ran a short sprint across Blanck’s Hanger clinic floor.

3 months later I could run several miles.

August 26, 2022
I ran on an all adaptive relay Hood to Coast relay team. I ran 3 legs of the course for a total of 17 miles in 24 hours. My body shook uncontrollable for hours after the final leg. I wasn’t good enough. Time to go silent and train.

May 23, 2023
I finished my first half-marathon.

April 13, 2024
I finished my first 50k.

November 22, 2024
I finished 45 miles.

February 15, 2025
I finished my first 50 miler.

November 21, 2025
I finished 100k.

March 8, 2026
I finished 100 miles.

Not one of these distances happened without relentless work spanning years. When I say relentless, I mean I spend more hours on my feet than many elite runners—because it simply takes me longer to finish the same weekly mileage.

And I train beyond the mileage.

I train as a hybrid prosthetic runner.

Along the way there were:

  • pressure sores
  • constant device adjustments
  • a complete rebuild when my leg changed
  • and a broken foot that I ran my 50-miler on

But through all of it, I never allowed myself to focus on not finishing.

Only on what came next.

Each finish line became the starting line for the next goal.

First one mile.

Then one hundred.

I share this timeline because I was born with severe birth defects from my face to my lower limbs.

I was never supposed to walk.

Despite archaic disabling surgeries...

devasting setbacks...

and negative prognoses from every doctor who examines me...

I still go far.

And this year will be my best running year yet.

Because when you believe the story is over…

that’s often just the moment you turn the page.
