THE LAWLESS 7/19/25

Race Classic Michiana Singletrack

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.

A NIMBA Tradition

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.
