HOUGHTON — Isle Royale National Park became the site of a record-breaking endurance feat this month when Michigan Technological University assistant Nordic ski coach Kristen Monahan set the fastest known time by a woman on the park’s Greenstone Ridge Trail.
Per a Sept. 23 news release, Monahan finished the 40.6-mile route in 8 hours and 4 minutes, nearly three hours faster than the previous women’s record of 11 hours and 2 minutes set in 2021 by Alice Held.
She was joined by her partner and fellow MTU Nordic ski coach Thomas Smith, who posted the second-fastest men’s time ever recorded on the trail.
The pair completed the self-supported effort while carrying their own supplies, filtering water along the route and navigating the park’s remote backcountry.

“This was more than just a race against the clock,” Smith said. “The real purpose was to experience the adventure and explore the island. We’re really stoked about Kristen’s time, but even more grateful for the chance to share the trail with others and experience Isle Royale’s incredible beauty.”
The Greenstone Ridge Trail spans the island with more than 5,100 feet of elevation gain.
Monahan said the challenge required careful planning, including ferry logistics and a nutrition strategy of about 100 grams of carbohydrates and 300 to 400 calories per hour.
The duo faced obstacles unique to Isle Royale, including a moose that forced them to bushwhack through the woods.
Monahan said the journey was special for its sense of community and interactions with other visitors.
Their accomplishment has been submitted to Fastest Known Time, the global tracking authority for endurance records, for official recognition.
“This achievement showcases not just world-class athletic ability, but also the incredible adventure opportunities found in the Keweenaw and Isle Royale,” said Brad Barnett, executive director at Visit Keweenaw. “We’re proud to celebrate Kristen and Thomas for pushing boundaries and highlighting the rugged spirit of our region.”
