From the Freedom Trail, this trail starts with a short but furious uphill section heading west and a fast, short saddle rising into another short climb. A sustained downhill section follows. The singletrack then enters into a longish climb and passes the entrance to the Proving Grounds Advanced Drop at left. Alpha then becomes a series of descents, rises, and switchbacks among many small ridges, and eventually crosses a long wooden bridge and passes the Landing Zone before heading back north. The return has a fun jump, a challenging uphill section and ends with a wooden berm and wooden bridge features and some last downhill fun—ending at FreedomTrail just south of the Alpha entrance.
