Phase 2.1 is simply an addition to Phase 1 with an added level of difficulty. Most notably, there are a couple of logs that you can go over.
However, all-in-all, this trail is similar to Phase 1. It is has a good flow with lots of twists and turns. As you become familiar with Phase 1 and want more of a challenge, adding Phase 2.1 will help you progress your bike handling skills.
