2013 Sandmine Challenge is still on. Please show up for your scheduled race time. We look forward to seeing all of you at the Crystal City Underground!

~4 Mile Underground Challenge Run!
Run through obstacles in an old sand mine then enjoy a Post-Race Party with music, beer, and food at the finish line!

NEW in 2013: EXTREME QUAD
Think you have what it takes to sperunk 4 times around? Test your limits by registering for Extreme Quad. It is still an underground race and you will still run, hurdle obstacles and tiptoe through "quicksand". Only it will be four times around and will push you to your limit - if you can make it!
