The Marin trail really is one of the most fun trails around. The weird thing is you hardly ever see anyone on it let alone get held up. Why people don't ride the Marin trail more often is a mystery, it's so good. This is my first video from a trail centre where I kept all clips in chronological order so you get a feel for how the trail progresses.
All filmed on a GoPro Hero 2 in 1080p 30fps and with a chest mount.
