The Sixth Annual Quarry Crusher Run will be held at the historic Olympia Quarry in Columbia on April 14, 2018 at 8 a.m. Starting and finishing at the green space in front of the impressive Olympia and Granby Mills Apartments in the Olympia Village, the foot race will afford a behind-the-scenes look at the magnificent landscape of the environmentally-responsible, operational quarry to participants. The approximately 3.72 mile route winds down a 10% grade through granite cliffs to the quarry floor. The 375-foot ascent from the quarry floor to the finish marks the grueling event as Columbia’s most challenging foot race! More info at www.quarrycrusherrun.com.
