We explore speed climbing, a unique competitive discipline that sees 2 climbers race to the top of a standardized 15m wall. Japan's climbers have traditionally been strong in bouldering and lead climbing, however, the advent of combined events that include speed climbing has prompted a concentrated effort to slash times. We check in to see what progress is being made and also meet speed climbing specialist Ikeda Yudai, who helps us analyze the innovative technique of world champion sport climber Narasaki Tomoa.
