This one usually goes hand in hand with fear of injury, logically enough, as you’ll be concerned you might injure yourself.

Advice: Build up to it. Find a similar obstacle on a smaller scale, and practice it until you are comfortable. Then size up, and repeat the process. When it comes to trying the obstacle you are fearful of, keep calm, and focus on remembering what it felt like to ride through the smaller obstacles. Stay relaxed on the bike, look ahead to the end point if you can, and before you know it you’ll be through. Some people also find that having done it once, it can be helpful to do it a few more times in quick succession to cement the experience firmly in your head.
