What are the race conditions and obstacles?

Non-standard distance about ~3 miles in the constant 56 degree sand mine, with obstacles approximately every 1/2 mile. Be prepared for the following possibilities:

  • climbing

  • wading

  • hurdling

  • balancing

  • crawling

  • navigating up sand dunes

  • and running over "quicksand"


The course winds through an old sand mine so it is almost entirely on a sand surface: some wet and some dry, some deep and some shallow. Prepare to be challenged!

You may be outside of the mine to begin the race so be ready for a climate change.

What is the entry fee?

The money raised through the Sandmine Challenge benefits Payback, a St. Louis area non-profit that works in partnership with Metropolitan St. Louis Area Family Courts to help children, their families, and our community break the cycle of juvenile delinquency through funding and administering restorative justice programs for juvenile offenders and their victims.
