There are many rollers on the trail which you pump, manual or link up and double if your speed allows. Access this trail by taking the right fork off of the blue line at the top of Gunjin. It joins up with Lazarus at the power lines and continues in to Alchemy after Loco joins and when the gradient flattens out.
