Stopped on way to visit family in NE. A strange mix of trail types. The "green" trails are largely open meadow trails, pretty flat. Although sections climb pretty steeply, although those sections are usually highlighted as "red". The "singletrack" is cow-trampled trails, so can have "deep" areas, some as deep as 6'. The troublesome areas are those about 18" deep; still narrow and can be difficult to pedal through.
Each trailhead has a set of maps, showing loops of green, blue and black difficulty. I tried to do the blue loops, starting at the west trailhead. Got lost a bit and had to improvise. Having said that, the intersections are largely well marked, and if you download a map from the North Platte bike shop site, you shouldn't get lost.
Also, some cow pies in the trails to avoid, and of course cows. Usually they scurry when you get close, except the mother's with calves, which have to be shoo'ed a bit.
Trail goes up/down pretty frequently, so you will do lots of elevation. The elevation gain is indicated on the various map loops by the local bike folks. The green loop stays usually on the wider areas, although there will be some climbing. I went up a trail not on the map; (can't recall the name now, starts with "T"). It had quite a bit of wood plank sections, and would be a blast going down.
Certainly was a fun ride; would definitely recommend it if you are in the area.
A little more detail on how to get to the west trailhead; exit I-80 at exit 199 (Brady), then south on Banner Rd for 2.7 miles, take right on Brady-Morefield rd for 6.7 miles. At this point, continue on the dirt road for 0.6 miles. Trailhead is well marked on the left.
