In the speed slalom, athletes must accelerate within a 12-meter distance and then sprint around 20 cones, spaced at 80 centimeters apart. A penalty of 0.2 seconds is incurred for knocking down any cone or missing any interval between the cones.

Roller sports at the Chengdu World Games feature three disciplines - speed skating (road and track), inline freestyle, and inline hockey. Two more freestyle skating golds will be awarded on Sunday.
