Garmin, global leader in fitness tech and pioneer of the world’s first running smartwatch, today announced the Garmin Marathon Series. This exciting new road running race flips convention on its head. While many brands sponsor races, this one is wholly owned and produced by Garmin itself, from start to finish.

With its inaugural event set for the fall in Toledo, Ohio, the Garmin Marathon Series will celebrate the ‘Miles That Made You,’ as Garmin truly understands the journey of a runner. Uniquely created for those who know and love its products, the one-of-a-kind event will welcome avid runners, newcomers to the sport, Boston dreamers and anyone just looking to beat yesterday.

“This is an opportunity to go above and beyond conventional sponsorships and create something truly special in our running communities. For decades, Garmin has been with runners through every step of their training, and now we are excited to be with them in an even more meaningful way on race day.” – Susan Lyman, Garmin Vice President, Consumer Sales and Marketing

The Garmin Marathon Series team selected two US locations for 2025: Toledo, Ohio and Tucson, Arizona. Factors included each city’s existing race and event schedule, regional run communities, local and cultural highlights around the course and favorable weather conditions. More locations are planned for 2026.

The Garmin Marathon Series will host its races in Toledo, Ohio on September 21, 2025.

The event will include a USATF-certified and Boston Marathon qualifier full marathon, USATF-certified half marathon, 10K and 5K. A two-day expo showcasing Garmin products and technology will precede race day and be open to the public. Attendees can expect limited edition race gear from Garmin, meet and greets with Garmin-sponsored professional athletes and additional items from select sponsors. Directly following the race, a finish line festival – also open to the public – will give runners a chance to celebrate with local food, live entertainment and other activities.

“We’re thrilled to welcome the Garmin Marathon Series to Toledo and showcase our beautiful riverfront to runners from across the country. Events like this not only bring visitors and attention to our city—they highlight everything that makes Toledo special: our vibrant downtown, scenic parks and trails, and the incredible sense of community that makes people proud to call this place home.” — Mayor Wade Kapszukiewicz
