Confirmed from Grissom Trailhead's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

Excellent trail to either walk, run or bike. Clean, wide trail that goes on for miles, a lot of shade all throughout and mile markers every now and then.
Maybe one day we can travel out of state on these trails... anything can happen! Who do I talk to about adding more Greenway trails?
Overall me and my wife enjoyed our 3 mile walk. The further we walked the more beauty we saw of the trail. It didn't start off so beautiful. There was alot of rubbish and areas that could have been tended to. We like the courtsy of most of the bike riders letting you know they were coming through.
