Who We Are

THOR is the International Mountain Biking Association Chapter for Eastern Nebraska and Western Iowa. Founded in 1996, THOR builds and maintains most natural surface trails and trail systems in Eastern Nebraska and Western Iowa through agreements with city, state, and other public and private land managers. Our education programs focus on youth trail users, land managers, and the building of sustainable nature surface trails.


Our vision is natural surface trail systems close to and integrated with communities that support active outdoor recreation for all ages, races, incomes, and abilities. We believe trails, connectivity with nature, and safe outdoor spaces create healthy and resilient children and adults, vibrant neighborhoods, and are foundational in attracting and retaining families, employees, and businesses.


Our mission is to create and share the natural surface trail experience in Eastern Nebraska and Western Iowa through advocacy, education, and building sustainable and accessible trails.



Our work supports present and future generations’ communities, wellness, economies, and public lands. We believe mountain biking and active outdoor lifestyles bring communities together, keep neighborhoods healthy and diversified with strong economies, and protect and expand outdoor spaces.


We share a responsibility to protect our environment for its intrinsic value so communities can cherish the great outdoors. We promote sustainable trails to minimize impacts on the environment, natural resources, and wildlife. We educate mountain bikers and other trail users to reduce environmental impact and help protect natural spaces.


We recognize a strong community must be a diverse community—we encourage, embrace, and celebrate diversity and inclusion. We promote equity and inclusion amongst trail users and work toward increased trail access to ease entry into the sport of mountain biking. We want everyone to experience the joy of running, hiking, and cycling off-road.


Collaborations are vital to our success. We frame partnerships on shared values and common goals to change lives by building welcoming and inclusive communities of trail users. We believe in working together to build, advocate, and use trails responsibly. Our partners include cities, states, private landowners, and neighborhood, community, and philanthropic organizations.
