Friends of Great Lakes Endurance:
This is farewell. After 26 years of race directing and building Great Lakes Endurance, we have decided to retire from organizing trail running events. After much thought and much consideration we made the difficult decision to retire. We will always remember the wonderful friendships we made through organizing our trail running events in such welcoming communities.
We founded Great Lakes Endurance on the concept that trail running could be a very powerful tool to help build ecological awareness and respect for the natural environment. We believe our goal has been achieved through the many unique and beautiful venues in Michigan and Wisconsin.
We are grateful for the enduring and lasting memories we will have from our trail running events and the many participants who have shared their stories of accomplishing a goal, running in memory of someone, in honor of someone or wanted to participate in an ecologically mindful event organized by us.
We are very fortunate to be able to hand over the reigns to Aravaipa Running. Jamil Coury and his team at Aravaipa have the experience, skills and passion we feel are necessary to take over Great Lakes Endurance. Aravaipa understands and respects the historical traditions established by Great Lakes Endurance and we are assured they will welcome the devoted community of runners and volunteers that we have grown over the years.
See you on the trails,
Jeff Crumbaugh

Young runners provided a glowing beam of hope for the future of trail running at the 2025 Tahqua. In the 25K, 15 year old Fenlynn Johnson of Rogers City, MI blazed the challenging Tahqua course in 2:29:35 to capture the overall women’s title. Moreover, she finished third overall in a tough men’s field. This was the third GLE event for Johnson in 2025. She also captured the overall half marathon title at the Two Hearted Trail Run on June 21 and finished 2nd among the women in the highly competitive Grand Island Trail Marathon (4:02:58) on July 26. In the 10K 14 year old Joshua Keillor of Boyne City, MI cruised (and hopped, skipped and jumped) from the Lower to the Upper Falls in 46:46, nearly two minutes ahead of his nearest competitor to capture the overall title. There were more runners in the 12-14 age group in 2025 than in the history of the Tahqua Trail Run. Keep in mind, the Tahqua 10K is considered the most challenging 10K in Michigan. Watching these young trail runners was inspiring and bodes well for the future of the sport. And at the same time the competitive field was beautifully bookended with veteran master 70+ runners including Barth Zurbuchen (70), Gerard Wilbrink (72) in the 25K and Robert Courtright (74) in the 10K.
Fenlynn Johnson (Rogers City, MI) and Jeffrey (Kalamazoo, MI) overall winners of the 25K. Their times were 2:14:59 and 2:29:35 respectively.
The 25K, considered one of the classic point to point courses in the Midwest saw Jeffrey Davis of Kalamazoo, MI jump out to early lead and he never looked back, finishing first in 2:14:59. Five minutes back in 2nd was Sean Munro of Northville, MI (2:19:23). Jeffrey Hicks of Coloma, MI completed the men’s podium, crossing the line in 2:40:50. Fenlynn Johnson, with her bold and strong running style, earned the overall title (2:29:35). Fiona Scott of Petoskey, MI also demonstrated remarkable trail running skill, finishing 2nd (2:42:52). In an equally impressive finish, 60 year old Jean Seward, competing on par with the talented teenagers in front of her, completed the top trio of women, finishing in 2:57:09. It is a notable achievement for any runner to complete the Tahqua 25K in under three hours. Joshua Keillor (Boyne City, MI) and Marissa Lobert (Sault Ste. Marie, ONT) , overall winners of the 10K trail run. Their times were 46:46 and 57:42 respectively.
The 10K, which includes an abundance of roots, rocks, staircases and a net elevation gain, witnessed a impressive array of finishers. As noted Joshua Keillor captured the overall title (46:46) while Samuel Ohland of Portage, MI followed in 48:48 to finish 2nd. Leif Briggs-Lind of Bay City, MI rounded out the top trio of men’s runners, finishing in 52:08. Briggs-Lind had previous racing experience on the course, finishing 3rd in 2023, albeit his time this year was 5 minutes faster. Marissa Lobert of Sault Ste. Marie, ONT earned the overall women’s title in the10K, crossing the line in 57:47. Joining Lobert on the podium were Sarah Larson of Lake Odessa, MI (1:09:34) and Jenna Briggs-Lind (1:12:30).
Leif Briggs-Lind and Samuel Ohland, 3rd and 2nd overall in the men’s 10K recover and share stories at the GLE refreshment tent.
Perhaps more than any other race, the Tahqua exemplifies the welcoming and inclusive community that GLE works to build. Many runners return every year for this experience, including the Lepard family, for whom the Tahqua has become an annual tradition. Their graciousness and appreciation has been a hallmark of the Tahqua. And Jennifer and Richard Hodge of Bay City, veterans of nearly all GLE trail races, whose relaxed approach to racing has so much to teach us all about the sport. It has been a joy to watch and listen to the entire Tahqua crew of participants over its 18 years.
Enjoying the post race atmosphere (L to R): Juliette Barnhill (Columbus, OH), Kimberly Robinson (Columbus, OH), Sharonda Williams (San Antonio, TX), Donyell After (Ashland, OH), Kerri Allen (Kentwood, MI), and Lynette Dawson (Helotes, TX).
Thanks and gratitude go out to our wonderful volunteers, including the crew from the Tahquameon Area Pathways Association who worked the aid stations, course monitors Roger and Diane Clark, the Luce County Amateur Radio Association, our medical crew including Peggy Moore, Amy Mayer and Pat Rowley and finish line crew members Aaron Deiter and Kent Walker.

A brilliant sunrise greeted the 50K runners as they started out past Murray Bay and into the Tombolo. On the course the forest canopy filtered the sun into focused beams and on the crystal clear water the sun danced about in diamond sparkles. At the finish line beach, runners basked in the sun’s warmth as the cooled down with a swim in Lake Superior. It was a good day to be on Grand Island. Complete results are available for viewing.

It was a collective trip back to childhood and the joy of splashing in rain filled puddles. But on a grand scale in the lush forests of Waugoshance. When setting up the course earlier in the week I noticed an abundance of wildflowers in the wetlands south of Goose Pond. Coreopsis, TigerLilies, Hare Bells, Shasta Daisies, Lady Slippers. And I knew this indicated that it had been a wet spring. Another indicator was a 20 ft section of calf deep water and yet another 50 ft section of trail underwater near Big Sucker Creek, courtesy of a local family of beavers. The frosting on the cake though, was a soaking thunderstorm moving through the region during the first several hours on race day. True to the tough and durable mindset of trail runners, we started seeing finishers at the Mackinaw School exclaiming, “That was awesome!” This was a refrain heard from smiling, mud spackled runners finishing all distances. Complete results are available for viewing. Runners from 14 states and Canada participated in this, the 14th edition of the Waugoshance Trail Run.
Shane Lishawa of Mount Shasta, California captured the overall title in the 50K with a time of 4:06:38, about 14 minutes off his course record from 2023. Shane, a ecological restoration research scientist, spends his summers working in Northern Michigan. Yooper Matthew Johnson (Negaunee, MI) was the only other runner to crack the five hour mark, finishing in 4:58:37. Ann Arbor’s Quinn Moon rounded out the men’s top trio, finishing in 5:08:33. Concetta Macko of Pittsburgh, PA convincingly won the women’s 50K in 5:27:31 and was the only woman to break six hours on the challenging Waugoshance course.

The 2025 Two Hearted Trail Run escaped the record setting heat that encompassed the midwest on June 21, but captured the dynamic thunderstorms on its edge. Light sprinkles at the start transitioned to steady rain as the system moved out along the coast and into Lake Superior, the world’s largest fresh water lake. Runners reported stunning views of the storm from atop bluffs overlooking Lake Superior around the 11 mile point in the 50K. The trail was is its best condition in the event’s history, but runners still encountered the big water hole at around 24 miles, reported to be thigh deep. Half marathoners endured the infamous bog at 9 miles. As is true to the character of trail runners, many finishers exhibited broad smiles and variations of “That was awesome!” Complete results are now available for viewing.
Joe Power Wayvon of Detroit, MI took the lead early in the 50K and held it for the entire route, finishing first in 4:24:42.
