The Quarry Crusher Run is in its 5th year? Why haven’t I run this before? The Quarry Crusher Run Series is held in 4 states (SC, GA, AL, MD). The SC run was held at the Vulcan Materials Company Quarry in Columbia. The race started a few city blocks from the quarry. Once you hit the quarry you went down into the quarry all the way to the bottom (they’re still digging!) and then painfully all the way back up. The out and back course averaged a 10% grade over about 3.7 miles.
