KRASNAYA POLYANA, Russia (AP) — Rider after rider took a crash course Monday night on an Olympic halfpipe that looked only half ready with less than 24 hours until men’s competition is set to start.

There were dozens of falls, very few big tricks and a lot of complaining during a practice session that was pushed from morning to night while workers tried to make fixes. The men’s event is Tuesday, and American Shaun White will be seeking his third straight gold medal.
