NIMBA is a not-for-profit organization dedicated to supporting mountain bike riding in Northern Indiana and Southern Michigan.
We are committed to the advancement of mountain biking through trail development, ride participation, and education.
Our objective is to encourage the participation of all ages and skill levels to join our mountain bike community.
The Lawless 50 is held annually at Dr. Lawless International Dark Sky Park in Vandalia, Michigan. There are three length options and multiple categories in each: the premier 50-mile race, the 2/3 Lawless (32 miles), and the ‘Lil Lawless (16 miles).
Tackle the challenge at your own pace, and try to ride all 16 regional trails this summer! T-shirt included with registration, and all proceeds go directly into funding local trail projects and trail maintenance needs.
Post your rides on the Michiana Mountain Bikers group and maybe get some others to join you!
