Santa Claus will be delivering gifts to children around the world this Christmas on a sleigh guided by reindeer but, in the meantime, one of his U.S. helpers is showing what would happen if jolly ol’ St. Nick went extreme. Ronnie Shalvis, a free-runner, stunt coordinator and parkour trainer from South Jordan, Utah, dressed up in a Santa suit and went to leaps and bounds, literally, to show how Santa Claus gets from roof to roof. Shalvis’ version of Santa travels by parkour, a running discipline that involves jumping, climbing and rolling anywhere and everywhere, making the landscape, in this case rooftops, a personal obstacle course.
