The Dog Run Marathon

Our dogs are there for the early-morning miles, the rainy-day jogs, and the everyday walks that make marathon dreams possible. But on race day, they're usually left on the sidelines. Today, that changes with the IAMS Dog Run Marathon - a race specifically designed to give our favorite training partners a marathon of their very own in partnership with Strava, the app for active people that lets U.S. pet parents track their daily adventures with their dogs.

This campaign by the IAMS brand, proudly part of the Mars family of brands, is part of the year-long partnership between Mars and Strava, launched earlier this year with the introduction of a new Pet Tag feature on the Strava app. The newly launched IAMS Dog Run Marathon gives runners and their dogs a shared goal and major milestone to conquer together with a month-long paws-on-the-pavement challenge built specifically to celebrate the unsung hero behind every logged mile.

Launched in partnership with gold medalists Tara Davis-Woodhall and Hunter Woodhall, this unique running challenge invites people and their pets to complete 26.2 miles over 30 days from Sept. 1-30, 2026, ahead of some of the country's biggest marathons. Participants can easily track every walk, jog, and run using Strava's popular Pet Tag feature with daily mileage capped at 5K to help keep every canine athlete active and full of life.

"Whether you're training to compete for World Championships or for your local race, it's never just about the finish line," said gold medalists Tara Davis-Woodhall and Hunter Woodhall. "It's the early morning workouts, the recovery runs, the days when motivation is low and you're showing up anyway. Our dogs Milo and Winnie are part of many of those moments with us, so we love that the IAMS Dog Run Marathon is giving dogs a chance to be part of the experience instead of watching from the sidelines."

"At IAMS, we know dogs are more than companions. They're partners in the active lifestyles we share together," said Mindy Barry, Chief Marketing Officer, Mars Pet Nutrition North America. "The Dog Run Marathon celebrates the dogs who show up for every mile, and IAMS High Protein is there to fuel their energy and recovery, keeping them in the day-to-day race, with a protein-rich recipe that helps keep dogs strong and healthy."
