Some cross country stuff, and a show name. (Kinda long)?

You can do lower level cross country even if your horse is not that fast. Beginner novice is about 300 meters per minute and Novice is about 350 mpm. 350 mpm is a moderate canter. Your horse does still need to be balanced and agile to do the jumps safely. Your next step will be some cross country lessons with your trainer. That might include an open schooling day at a real cross country course somewhere nearby.
