Running with
Type 2 Diabetes.
A receptionist called to tell me I had Type 2 diabetes. Then she hung up.
I decided to run World Marathon Majors instead.
The Goal
6 World Marathon Majors.
Not a bucket list. A statement. With Type 2 diabetes, managed in real time.

Who's running this
I'm Josh. I have T2D.
I run marathons.
A very picky eater whose diet used to be burgers, chicken sandwiches, fries, and steak — I built consistency without perfection, turned races into a fundraising platform, and started building tech tools to manage everything my doctors couldn't automate.
Every mile is an experiment. Every finish line is proof. I fundraise for Breakthrough T1D — the world's leading T1D research funder — because better diabetes science helps everyone, regardless of type.
The nerd part
I'm a solutions engineer. Of course I built tools for this.
Custom Garmin watch face showing my glucose mid-run. A Python CLI that reverse-engineers Abbott's API because they don't have a developer portal. A personalized effort score model trained on 158 Strava runs. An AI pacing coach that talks to my watch via Claude's API. Cost per run: ~$0.02.
