‘It was intense’: 75-year-old is the oldest person to finish the Arrowhead Ultra 135 on foot

The Arrowhead Ultra 135 considers itself one of the most extreme endurance events in the world. Which makes it an ideal match for Michael Koppy, a septuagenarian runner without equal in Minnesota.

The Hermantown, Minn., man hit the finish line Wednesday evening, Jan. 28, after covering 135 miles between International Falls and Tower, Minn. — at age 75, making him the oldest participant to complete the winter ultramarathon on foot. Racers also compete on skis and bikes.

Historically, about 58% of the field finishes the Arrowhead Ultra 135. Koppy was one of 32 entrants who finished on foot this year; 38 more dropped out during the race.

“It was intense,” said Koppy a week later, still in recovery mode. The tips of his fingers remained numb and his lower back was sore, but he is feeling satisfaction, too. This year’s result was redemption. At last year’s Arrowhead, he had to quit with only several miles to the finish.

Koppy covered the course along Arrowhead Trail in 59 hours, 30 minutes, just beating the 60-hour cutoff. Pulling a sled loaded with 50 pounds of food and gear, some of it required, he overcame an assortment of challenges synonymous with the ultramarathon.

The weather was true to the race’s billing: about 20 below at the 7 a.m. start on Jan. 26 in International Falls. The cold intensified as the wind picked up over the first 70 miles to the checkpoint at Melgeorge’s Resort in Orr, Koppy said.

“It was such a strong wind,” he said. “You put on everything warm you had and still weren’t warm.”

The Arrowhead 135 Ultra Marathon, from International Falls to Tower Minnesota, follows the scenic and rugged Arrowhead State Snowmobile Trail and attracts some of the best ultra-athletes in the world.

Plus, he was without some key fuel to start. Koppy relies on drinking half of his calories, but he mistakenly put powders containing electrolytes and carbohydrates in a resupply bag at Melgeorge’s, which is about midway. He compensated with water and energy bars, but he struggled with keeping the water thawed, and the bars didn’t sit well.

“That was the toughest stretch of the whole race,” he said.

Still, the cold conditions worked in some racers’ favor. The trail was firm, which provided good footing for Koppy and better glide for his loaded sled. He got a rest and made time by “screaming” down the biggest hills atop his sled.

The hard pack did not appear to benefit the race’s nine skiers, apparently. Only one finished.

Koppy barely slept during the race and took relatively short breaks at three checkpoints, including Melgeorge’s, before hitting the finish about 6:30 p.m. Jan. 28.

“Michael shows us what’s possible,” wrote race director Ken Krueger in a text. “He is an inspiration to this entire racing community.”

Koppy can add the Arrowhead Ultra to his long résumé of ultramarathon feats. He has completed nine 200-plus-mile trail running races. He is registered for a 100-miler in June in Wyoming and another 200-miler in July.

Koppy also holds the speed record for the 310-mile Superior Hiking Trail along Minnesota’s North Shore. In 2020, at age 69, he ran the trail in a little more than five days.

That over-the-top achievement is the only effort that compares with the Arrowhead, he said. “That also took every ounce I had out of me.”

He is considering another Arrowhead, but only on skis or a bike, he added. (He has 27 Birkebeiner finishes in his quiver, too.)

“They call [the Arrowhead Ultra 135] one of the hardest races on earth,” Koppy said. “If there are harder ones, I am not interested.

Bald eagles congregate on the ice, near an open stretch of the Mississippi River, below Lock and Dam No. 4 on Jan. 2, 2021, in Alma. During winter, much of the river freezes up and so bald eagles congregate near areas where the water is not frozen in order to hunt for food, including fish, which are a large part of their diet.
