Kasson’s Isaac Threinen completes fourth marathon at Twin Cities Race

Isaac Threinen of Kasson took on a new challenge this fall: the Twin Cities Marathon.
He finished ninth in the race.
Though no stranger to long-distance running, this was his first time competing in the iconic race that winds through Minneapolis and St. Paul. For Threinen, the decision to run was fueled by a summer spent training in the Twin Cities with the Collegeville Track Club.
“Being part of that community and putting in so many miles in the area made the Twin Cities Marathon feel like the perfect next step,” he said.
This wasn’t Threinen’s first marathon. He’s completed four full marathons and several half marathons. Coming off a spring run at the Boston Marathon, he launched into a focused 12-week training plan, peaking at 80 miles per week. His long runs stretched up to 23 miles, building both endurance and confidence.
Race day brought its own set of challenges. With temperatures hitting 70 degrees and strong winds, conditions were far from ideal.
“I knew early on that I needed to run smart and adjust my strategy,” Threinen said.
He stayed cool by pouring water over himself at aid stations and conserved energy by drafting behind other runners. A tough uphill stretch around mile 20 tested his mental toughness, but he pushed through, passing four runners and gaining a surge of confidence.
One of the most memorable moments came at mile 22, when Threinen spotted his running club cheering from the sidelines.
“It brought life back into me,” he said. “I knew I could finish strong.”
Support from friends and family along the course, and from afar, played a huge role in his motivation.
“Seeing familiar faces gave me an extra boost of energy when I needed it most,” he said.
For those in Dodge County considering their first marathon, Threinen offers this advice: “Stay consistent, and remember that training goes beyond just logging miles. Focus on nutrition, hydration and sleep.”
What’s next for this dedicated runner? Threinen has already signed up for the Boston and Grandma’s marathons in 2026. He’s also maintained a four-year daily running streak and has no plans to break it.
