Tudor Doubles Down On Trail Running With UTMB World Series Partnership

Tudor is now an official partner of the UTMB World Series, the global trail running circuit that culminates each summer at the HOKA UTMB Mont-Blanc in Chamonix, the series announced.

For the Swiss watchmaker, this is not a toe in the water. Tudor signed four of the world’s best trail runners earlier this year, a group headlined by Courtney Dauwalter, and backing the circuit itself completes the set. It is the classic luxury-watch playbook, the one Tudor’s big sister Rolex has run for decades in tennis, golf, and motorsport, now pointed at the mountains. And it is one more signal of how much mainstream money is flowing into a sport that, until recently, handed out finisher vests and called it a day.

Why A Watch Brand Wants The Mountains

The appeal is the difficulty. The series finale is a 106-mile loop of the Mont Blanc massif with 10,000 meters of climbing, temperatures swinging from -5°C to 35°C, a night or two without sleep, and a dropout rate around 40 percent. Even getting there is a multi-year project: entries are earned through the series, not handed out.

“In trail running, time is not only measured in hours, minutes and seconds,” the announcement reads. “It is measured in years of preparation, in tens of thousands of meters climbed, in nights spent running up and down the mountains.”

Since launching in May 2021 as a partnership between UTMB Group and The IRONMAN Group, the circuit has grown to 64 events in 29 countries across five continents, exactly the kind of global stage sponsors pay for.

The Watch Nobody Will Race In

The announcement is refreshingly honest about one thing: “Elite athletes typically don’t wear mechanical watches, but that’s not the point.” Nobody is running through the Alps at 2 am checking a self-winding chronograph; every athlete on the circuit races with a GPS watch. Tudor’s pitch is that the mechanical watch is the trophy, not the tool, “a totem to the unbreakable spirit” that gets memorialized after the finish line rather than consulted before it.

It fits a pattern for the brand, which also backs a professional cycling team co-founded by Swiss great Fabian Cancellara. Endurance suffering, it turns out, sells Swiss steel.

What Runners Will See

Expect Tudor branding across the series as it builds toward the finals in Chamonix, where Ruth Croft arrives as the reigning champion and Dauwalter, now a Tudor athlete herself, chases a record fourth title.

The announcement signs off with a message to this year’s field: “You’ve made it this far. Now the real race begins, and TUDOR will be there.”
