There are two kind of jump competitions at Unicon. Platform jumps and track jumps. The goal of both jump comps is to either jump the furthest (long jump) or jump the highest (high jump). Track jumps require the rider to jump over bars from the ground back to the ground, and platform jumps requires the rider to jump onto a platform from the ground in high jump, and from one platform to another in long jump.
Important: Know your starting height/length. You have 12 tries only, and it would be a shame to waste your tries on jumps that are too low compared to your skills.
