So, I know that you need to stop the dude on the quad-bike twice, but I don't know how to stop him. I know that I need to follow him at a canter and then gallop through that one shortcut that slips through the trees and you can cut him off there. However, I'm not sure what I should do to stop him. Do I stay on my horse or stop him? And after I stop him the first time, how do I stop him the second time?
