I recommend using the Discovery mode as opposed to Challenge for downhill videos. That way the video is not sped up and you can enjoy the fun for longer.
Hidden gem in the Sierras Nevadas, Downieville is a Gold Rush town that hosts a legendary mountain bike event since 1995, the Downieville Classic. In this video, Sunrise Trail is the very first trail at the top of the Downieville Downhill and starts right where the shuttle drops you off, Packer Saddle. It is a rolly twisty trail that is a good warmup for the rest of the downhill.
