On-line registration opens March 25th and SPACE IS LIMITED! Once this event sells out it is closed. Waves will begin at 9:00 AM with a new wave starting every 30 minutes!  The first three waves of the day are for the competitive runners who come to compete! Gather your friends, family, and co-workers and start training so you can take advantage of early registration savings...there is plenty of mud for everyone!

Registration Fees

The registration fee gets you a performance t-shirt (no cotton here), , awesome marked course, free beer (21+ only), race bib, and access to great food and music at the post-race festival!  Don't forget, every FFMR event benefits a non-profit organization as well!

We offer Filthy Fun incentives for team registrations!  Gather your friends and family and sign up for a Filthy Fun Mud Run!  Each participant on a team of 12 or more will receive a one-of-a-kind Filthy Fun Mud Run pint glass at the event.  The more the muddier!
