I've heard about climbing becoming an olympic sport for years. Cool that it did! This indeed does sounds weird though:

Sport climbing, to the chagrin of climbers and fans, was granted only one medal each for men and women. That forced organizers to smash three distinct climbing disciplines — speed, bouldering and lead — into one combination event.

They are different. Endurance versus explosiveness. This mixing will give strangely garbled leaderboards.
