Note - These Classifications will be used at

other Mud Runs in Maine this year.

Check back on this page to see locations

These classifications have been developed over the last 25 years and
are designed to make Mud Running fun and affordable for anyone.
Because of the years taken to develope there is little if no change from
year to year which makes it easier for racers to build and maintain their
unit.

racers that come from other regions to enjoy the challenge and fun
of the Might Big Pit. Come and we will have a Class you fit.
