Ryan's Eternal Flow (aka Ryan's Line) is very short, but very fast. For this reason, it's not recommended to stop anywhere on this line. You can access this trail by riding/walking up the Ryan's Connector near Bootcamp's entrance at the southeast section of the hub.
Ryan's Line starts with a drop to gather speed. Along the way there are many optional jumps and alternate routes to increase the difficulty. The last half of the trail offers quick bursts of speed rolling up and down different embankments, much like riding a half pipe made of dirt. Look for a rollable but quite tall ramp at the end of the trail.
Head left to the hub, or right to the overflow parking area.
