Echo State Park was by far the best part, though road got a bit bumpy over there. from Park City there are a few gates to get through. Mostly sun exposure, and watch out for gopher holes the first 7 miles

Ran about 10 miles this morning. As others have said, the northern half is the best. However, it’s a brutal, continuous uphill and not fun to run. Several huge undulations right off the bat. Combine that with the sun beating down and you’ll get absolutely worked over if it’s over 70 degrees. Spends a lot of the time straddling the highway too which I didn’t love. I would run it again but only because it’s the only longer trail around (that I know of)

The north end is great, paved with only a few traffic intersections/crossings. Then after Daybreak for some reason instead of asphalt the path parallel to the highway is a cement sidewalk with seams. It is also very messy, lots of rocks and debris. So you’re either riding on the sidewalk or the highway shoulder (the “bike path”). Once you get Grand View Peak Drive in Riverton the parallel path disappears completely and you’re on the shoulder. I only use the first 12 miles of this trail from 4100 South to Daybreak.

I road part of the trail from the Redwood Trailhead Park to the River Oaks Golf Course and back again. There is a severe lack of signage to show you the main trail and you end up taking lots of wrong turns or continually stop to check if you need to take a turn or not. This gets a bit frustrating as you don't get a nice flowing ride, but rather a stop start ride all the way. I think I took about six or seven wrong turns and had to back track. Other than that, the trail could do with some maintenance. There are lots of cracks due to roots under the tarmac and some of the bridges could do with resurfacing, but it didn't worry me too much. Forgetting about the negatives, it is a really nice ride along the river and you don't have to deal with traffic which is great. The view of the mountains is awesome especially as you get further south. If I'm in Salt Lake City again, I'll definitely ride this track again, but I'll bring my GPS next time as it will save a lot of headaches. I would recommend this track, but bring your GPS and keep an eye out for the strong southerly wind. Makes for a strong head wind on the way south, but great for coming back.

The first 14 miles traveling from Park City was all downhill and fast. Once we got to mile 17 until near the end the trail is in very poor condition. The horses and cows have torn the trail up and it was extremely hard to ride. It took us 4 hours in no shade to complete the trip. You must be strong and have a very good mountain bike to be happy with this section of the trail. Also all the dead deer on the side of the road were stinky and rotting (I counted at least 20), The trail follows I-80 most of the way and it is okay, but a little distracting. Now get out and ride !

Walked the trail south from Riverdale about 2+ miles after you cross bridge the trail is gravel but still a great walk there is several place to take a rest if you need to also couple of place to have a pinic a great trail for a walk or bike ride.

Great little trail it is paved and if you are a railfan you will love it. I walked it and the frontrunner was parked there so i got a pic of it and uploaded it here. If you want a nice short walk give it a try it is also a great trail for beginners. To get to trail head park on north side of parking lot and walk east on the north end of parking area and just before you cross rail look right for trailhead sign.

I rode from 4100 S. to the intersection with Redwood Road at Point of the Mountain and back. 18.3 miles one way. I think it is the entire length of the trail. For sure the south end was. It might have been a little more north of 4100 S.

Like the previous reviewer said, the first 9 miles or so are nice and well separated from UT85. After that not so much. The last 9.5 miles, from Old Bingham Hwy to Redwood Rd, you are riding along the fast moving traffic. The bike lane is painted on what should be the emergency lane.
Also, as the previous reviewer stated, this bike lane is covered with road grime. The only good thing about it is that it is wide. But I still wouldn't want to be there during rush hour.

This trail is not flat and was a good workout.

For me, the worst was all the trash along the trail, of all sizes. I'm hoping the cities along this otherwise nice trail are planning a spring clean-up.

This was my first time on this trail. Because of all the road grime (risk of a flat) and trash, I won't be on it often. I see myself riding it once or twice a year at the most... unless it gets cleaned up.

Seems a little like the Department of Transportation wanted to build a road, and then tried to balance negative environmental factors with a grade separated bike path.

Decent execution in the northern 7 miles of the trail, aside from some pretty dicey highway intersection crossings where the trail switches from one side of the highway to the other or has to cross an arterial road. Some major long rolling hills which make a good workout. I did it on inline skates and wished I had my brakes on.

The southern portion of the trail is poorly executed because instead of grade separated rolling hills, the trail is right next to the highway and covered in highway grime. Might as well use the regular bike lane (next to 70 mph traffic).
