Type One Run

It’s not in your head.

In the landmark study of what actually keeps adults with type 1 diabetes from being active, fear of hypoglycemia ranked first — above work schedules, above fitness level, above everything. More than 60% of people with T1D are sedentary.

The same research found two things that lower the barrier: understanding how insulin actually works in your body, and having someone to do it with. Type One Run is the second one — and often, in practice, the first one too.

Chapters from Los Angeles to Mumbai.

We’re a global running community with chapters from Los Angeles to Mumbai, organized by local leaders and a growing number of informal groups. We have a Couch-to-5K built specifically for people with type 1, and a Ragnar relay team. You don’t need to be fast. You need people who already know what a long run does to your blood sugar, and will tell you.

A Couch-to-5K built for type 1.

The hardest part of starting is knowing what to do on any given day. This plan answers that for six weeks — every run, every strength session, every rest day, laid out.

Managing blood sugar around it is a separate skill, and the simulators teach it directly: exercise timing if you take injections, temp basal if you’re on a pump.
