The 2026 Grandma’s Marathon is officially sold out! The only way to secure your bib is through the Charity Partners Program — and we’re thrilled to be one of them!
Named for its flat, scenic course, this iconic race is perfect for runners ready to take on a Full or Half Marathon challenge. We have a limited number of bibs available for our team. Registration is now available — complete the interest form below to be among the first to know and secure your spot.
While there is a fundraising minimum, you’ll have personalized coaching, team support, and a wealth of resources to help you reach your goals. Every mile you run helps improve the lives of those living with hydrocephalus.
