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.
Choose between 15, 30, or 50 miles of classic Michiana singletrack at the rugged TK Lawless Park in Vandalia, Michigan.
The 50 mile course is Northern Indiana's toughest trail race. Finish this and you have some serious bragging rights!
For most, the 30 mile course is just the right amount of singletrack mixed with rugged hiking trails to be an epic day. eBike category available on the 30 mile course.
Want to all out sprint? Consider the 15 mile course and let 'er rip.
This is our annual mountain bike race and our largest fundraising event of the year. Funds raised by this event go directly back into our trails.
We use these funds to reinvest into our trail trimming equipment & purchase materials to modernize our trails with features like berms, jumps, & pier drops.
Please be mindful of how freeze/thaw cycles affect the trail surface.
As temperatures move from multiple days of freezing to multiple days of thawing, the trail conditions get muddy, slippery, and likely rutted while riding. Use trails while the ground is frozen.
Do not use trails when they are thawing and muddy.
Once above freezing, wait until the trail dries out. The winter can be especially challenging to deal with ruts, because once the trail freezes back over, those ruts become semi-permanent trail features that are no fun to ride on.
