Presented by Dan Clark, also known as Nitro of American Gladiator lore.  The “Voted #1 Mud Run in the USA” returns to the Pacific Northwest!
Get ready for the “Most Insane Day of your Life” as you run, slide, jump and crawl your way though piles of mud so thick and dark, by the end of the race you’ll see the world through muddy eyes.
But Gladiator is more than just mud. Prepare yourself for 5 kilometers of collective scampering over 17 Obstacles as you bound over walls, rocket down Skid Marks and conquer the Beast on your way to Gladiator Glory at the finish line.

After the event, you’ll celebrate like a Gladiator God and rejuvenate your mud-splattered soul with beer, food and rock 'n' roll.
So make Poppa-Nitro proud. Throw caution to the wind and sign up today for the “Voted #1 Mud Run in the USA!”
