I hiked this morning from the trail head back toward Zilker crossing under Mopac for a bit before turning around. The hike is easy, but I agree with former comments that the uphill at the end of your hike is what makes this a little more difficult. Otherwise I would have only given it a 1 or 2. Pleasant hike that you don't have to weave around to try to get some distance but there was a number of bikes and a pretty busy trail. I would say that we passed/were passed by at least 50 people on the trail for just shy of 2 hrs.
