The official Red Bull Rampage build team — onsite for weeks ahead of the event installing a few select features and handling some of the bigger build projects — has officially handed the shovels over to the athletes themselves. Each rider is scouting their own line according to their individual skills and style, and the routes taking shape are looking super gnarly.

In the video above, builder and judge Randy Spangler explains the course build process, while Andreu Lacondeguy and Mads Haugen start guinea-pigging lines and kick off the sunset sessions on the step-up.

Watch the athletes take their unique approaches to the mountain in the live webcast of the finals on October 13, 2013, starting at 1:00 p.m. MT here, on the official Red Bull Rampage site.
