Just a reminder: parking at the north parking spot on the maps is extremely limited. There are only 14 parking spots - show up early or detour to the south lot.
Adobe Jack starts with compacted dirt on a smooth trail, compared to the much rockier trails in most of Sedona. The trail winds around on the natural contours and dips in and out of small washes and forest. As you get lower, it gets a little rougher and rockier. It lacks the grand vistas of other trails in Sedona, but it's still a super-fun run.
