Don't let the title "Difficult Run" fool you--it's named after the stream it parallels, not its level of difficulty. There's nothing technical to speak of here--unless you like the technical nature of erosion, washouts, mud bogs and consistent hoof damage. The mud bogs remain even long after any rain. The trail sees no maintenance, so the ravages of the traffic and weather go unchecked. The trail's not all like that--the western portions are better than the eastern portions. If the whole length was as good as the western end, I could give it three stars, but the east end barely rates one star. There are better trails in the area.

Nice ride from Lake Fairfax to Great Falls.
| ThankTrail has improved over the years, climbs, rocky downhill, technical areas, and some nice jumps
| ThankI've biked through the creek before as long as it's the summer and the water is low. Just get some speed into it because the rocks on the creek bottom are slimy and you don't have a lot of traction.
| ThankBoggy in some spots. A couple creek crossings. Not overly hard except for the climb at the end into Great Falls Park. You can join this with Colvin Run for a good mix of trail.
| ThankYeah I tried to ride over the rock bridge, I FAILED, but I tried. I just tried to go as fast as possible and did some hops over some of the gaps between the rock.
| ThankRidden here a handful of times and always enjoyed it. It's more of a family ride than anything...definitely not hardcore singletrack. The trail is like a hybrid xc trail/walking trail. Wide in parts with rocks and stream crossings, legit singletrack in some parts. BEAUTIFUL scenery if you ride all the way to Great Falls.
| ThankI started on this trail and return to it every so often for a good early weekend morning work out. It has its share of narrow passes, average climbs and down hills, and a couple of water crossings (if you take it all the way to Great Falls). In the morning, you run the risk of surprising dog-walkers, but the trail really begins to get crowded as the day wears on.* Review edited 6/6/2011
| Thankvery nice endurance trail not to crazy technical, MTB virginia guide book says to start in Reston i however started around great falls off GT pike and went out and back very cool and it connects with some single track in the park
| Thankthis is a good trail for people who r getting in to mountain bikind. But it is also not strait and that easy. There are some steep hills and some high creek crossings. I love it though!
