Tough Mudder is coming back to Northstar and dishing out just as much dirt as before. Whether you are looking for repeat punishment, or a new-timer, there will be two days of challenging, painful and dirty obstacles for you to undertake. The 10-12 mile obstacle course is designed by British Special Forces created to test all-around strength, stamina, mental grit and camaraderie. This event continues to help raise millions of dollars for the Wounded Warrior Project. You can sign up for races on either Saturday, Sept 28th or Sunday, Sept 29th. You also have the option of being a spectator to cheer on the daring participants. The proceeds from purchasing your ticket go to help support this important foundation. Tough Mudder is the world’s premier adventure challenge series. For more information, please visit ToughMudder.com.
