Figured I'd make a thread about this since its been mentioned before. My brothers and I are signed up for the mid-atlantic Tough Mudder competition down in Frederick, MD. The date is September 8th, registration fee is about $150...proceeds go to the Wounded Warrior Project.

I also have a discount code that will bring the fee to $107. PM if interested
