The Type 1 Diabetes Run Across America

2845 miles. 90 days of running.

Completed Wed., April 7, 2021

"The antibody tests came in. It's Type 1 diabetes."

First comes the diagnosis of a lifelong, incurable autoimmune disease.

Then the justified fear of dangerous, even deadly, low blood sugars.

"How can I even let my child play outside? What if her sugar drops?"

"I used to run marathons. Now I'm scared to even train. How will I ever do this again?"

I overcame my own fear by watching, listening and learning from other Type 1's.

Now, I'm paying that forward, showing that we can still dream big and connecting T1s to each other so we can all chase our dreams.

Epic is for Everyone!

Just a few of the amazing people with Type 1 diabetes, families, and supporters who I've met on my trans-state and transcontinental runs.

Happy to answer questions about how I do this despite Type 1--just DM me on Facebook or email me.
