Breakthrough T1D at Grandma’s Marathon

About

Breakthrough T1D is an official charity partner for the 50th Anniversary of Grandma’s Marathon, taking place June 18–21, 2026 in Duluth, MN!

This milestone year is expected to sell out quickly. Once general entry is full, the only way to secure a bib is by running with a charity partner like Breakthrough T1D. That means now is the time to claim your spot and be part of this historic race weekend!

Team Breakthrough T1D will have bibs available for the full marathon, half marathon, and the 5k.

Every mile you run and every dollar you raise will advance our mission to improve lives through life-changing research, advocacy, and support for people living with type 1 diabetes (T1D). Together, we’ll make an impact that lasts far beyond the finish line.

👉 Early bird applications are open now! Don’t wait, spots will go fast. Apply here: Breakthrough T1D Grandma’s Marathon Application

Let’s make this golden anniversary race one to remember! Join Team Breakthrough T1D and run for a world without T1D. 💙
