If you are using the Racing Strider, and you are wondering why the Jump to Banner button doesn't work and gives a notification "You have no target." The next banner has to be fairly close for this ability to work, maybe "15 yards" in game distance. If you're too far away you get "You have no target." You don't actually have to "target" the banner (e.g. click on it or tab key), you just have to be close enough.
Also, you don't have to go through all the banners, or any of them (except the Start banner). All you have to do to complete the quest is go through the Start banner with your Darkmoon Game Token, get near each of the colored posts in the correct order, then go back through or near the Start banner. Going through some of the banners poses a nuisance with electrified wire hazards or an unhelpful buff, so you can just follow the banners as a general guide to keep on course and go around any banners if you don't wish to go through them.
