Garmin’s Marathon Series just showed up in an EU trademark filing

Garmin has filed GARMIN MARATHON SERIES as a European trademark, covering everything from running events and coaching to race timing and participant software. The filing lands at an interesting time as the company builds out a much bigger running and race-management operation.

What the filing actually covers

The application, numbered 019424042, comes from Garmin Switzerland GmbH and it is not just protecting the name Marathon Series. It stretches across two Nice classes.

Class 41 is the expected one. It covers running marathons and races, coaching and training services, and it also pulls in cycling, strength training and triathlon, so Garmin is protecting a much wider chunk of the fitness world than the name suggests.

Class 42 is the one that catches your eye. It covers software for timekeeping, participant identification and communications at sporting events, plus consultancy and development work around that same tech.

There is no Class 9 anywhere in the filing, which is the category that would normally cover watches or downloadable software, so there is nothing here pointing towards a new wearable. This is about events and the technology that runs them, not hardware.

Garmin’s marathon series is not new, the EU push is

Worth being clear here, because it would be easy to read this as Garmin dreaming up a brand new race concept. It announced the Marathon Series back in April 2025, and it made a point of saying the races are wholly owned and produced by Garmin itself rather than just sponsored.

Toledo and Tucson hosted the first two events in 2025 and Durham, North Carolina joined as a third US city with its first race in May this year. Garmin has since folded those events into a wider Garmin Run Marathon Series that now spans thirteen cities across Asia and the US. Runners who complete ten of those thirteen cities between 2022 and 2027 even get a special gold plated medal for it.

Not one of those thirteen cities is in Europe. That is what makes the EU filing worth paying attention to.

So is a European marathon actually coming

An EU trademark application does not mean Garmin has booked European venues or picked its next marathon cities. At least, not publicly. Companies regularly protect brands in markets where they may want to operate later, and Garmin could simply be making sure the Marathon Series name is covered before somebody else causes problems with it.

The breadth of the filing may be the bigger clue anyway. Garmin is not just protecting a name. It is protecting sporting events, coaching, timing systems, participant identification, communications and software development around those events.

The company already has the watch on the runner’s wrist, the training platform before the event, its own races and now the timing technology on race day. Whether Europe becomes the next stop remains unknown. But it is looking likely.
