The Ontario Ultra Series (O.U.S.) GRAND SLAM challenges seasoned ultra runners to complete all three of the longest races in the Series within the calendar year. Few are expected to rise to the challenge and even fewer are expected to realize the goal. By its very nature, the GRAND SLAM will push both physical and mental boundaries, recognizing and rewarding those that complete it. New in 2014 is the Petit SLAM.
