About Woldumar Trail Run

Runners, walkers, and nature enthusiasts! You are invited to enjoy the beauty of fall on the trails at Woldumar Nature Center.

Join us on Sunday, November 1st for the 18th Annual Woldumar Trail Run presented by Lake Trust Credit Union!

The Woldumar Nature Association is a Lansing, MI based nonprofit that engages over 7,000 students in outdoor education each year. You'll enjoy the beauty of our prairie, pine forest, wetlands, and hardwood forest as you run along the Grand River on over 180 acres protected by the Association.

Not only is this the perfect fall run on a beautiful course, but most importantly your participation supports quality science education that instills passion for the natural world in young people throughout the Greater Lansing Area. Your support furthers our mission: "To educate people about the natural environment."
