Rode the SRT from Broadhead to New Glarus on Friday 10/25. Great scenic trail but some maintenance is needed, passed four down trees blocking the trail. Also some holes made by some critters you would not want to hit. Most of the mile markers were gone.

I mostly ride the crushed Gravel from the Genoa City Parking area down to Petersen Park. The trail is well maintained, although some of the asphalt is in need of some TLC. All-in-All, it's a 5 star trail as is most of the trails in Illinois. The parking areas are well maintained and convenient with Bathroom facilities and water.

I have been riding this trail for 10 years now and it is awesome. I ride a MTB and a drop bar gravel bike and both are well suited for any conditions on this trail. I personally love to ride thru mud and water...it's just plain fun as is this trail.

This paved trail is a short (3 mile) north-south connector between two more prominent east-west rail trails -- the Lake Country Trail and the Glacial Drumlin State Trail. The route in its entirety parallels Cushing Park Road, running for more than a mile along the western edge of Lapham Peak State Park and Evans Prairie, where views of prairie grasses and wildflowers can be enjoyed by passing bikers and hikers. Elevation changes over the gently rolling terrain are easy to negotiate.

I returned on one of those great Midwestern fall days to complete the portion of the Glacial River Trail south of Jefferson. I found the few miles that were in-fact a former railroad. The rest of the trail is in the WI-26 freeway corridor or on rural roads and city streets, but the trail is all paved.
The city of Fort Atkinson is very attractive with trail amenities including public art. I again found that the TrailLink map was a necessity as the signage on the tail is sparse.
My only negative is there is no need to do the on-highway portion south of N Wright Rd unless you want to continue to the connection to the Spring Brook Trail that will take you into Janesville.
For an out and back trip consider places where you can use the parallel old WI-26 for a different landscape view.

Plenty of space to park stock trailer in gravel lot on Lake Shore Rd Clinton. Cute little covered bridge in small park with picnic tables was the start of my mule ride. There were trash receptacles, handicap accessible restroom & a wood post hitching rail. Many "sponsored" rest spots with wooden benches, picnic tables & some had roofs along the flat trail. Trail bed is wide, flat & firm as small crushed gravel & grass base. Views of plant/tree farm & rural properties after brief bit of SE side of Clinton. Mileage markers. Several blacktop road crossings. Easy, well-groomed trail. Small gravel lot at east end with trail map on kiosk. For lunch at Boar's Nest Bar ride Hill St (right uphill), stay right on Clinton St, quick Left along west side of the Park 1 block to stop sign Cty X. Ride directly across Cty X then straight across grass to cable picket line.
I-43 runs parallel to trail. Loud traffic but distance kept equines from becoming unnerved 🙂 Met a jogger, a hiker with a leashed dog on trail & 2 bicyclists at covered bridge. All were respectful of equines.

If you are looking to take it easy and just go for a nice ride this is it. Smooth and simple. Very well maintained.

The Glacial River Trail in the Rock River valley is untypical for Wisconsin state trails in that it is entirely paved and not a rail-to-trail. It has a great mix of segments in the WI-26 freeway corridor, city streets and rural roads, with some good grades. I did the north part of the trail from Jefferson to the junction with the Wild Goose State Trail. There are no services provided by the trail owner, but the trail is free to use. The signage for the trail-turns is minimal so the Trail-Link map downloaded on your smart phone is a must. I especially enjoyed my ride thru the river towns of Jefferson, Johnson Creek and Watertown, where I took the time to ride around the downtowns. I will come back someday to do the south portion.

We got on the trail at Lacy Street in Verona/Fitchburg WI. The trail was paved and in great shape at that point. Cyclists were using it as a commuter trail and there were several people out walking and running. The trail turned into non-paved surface and that is where we dismounted to pay the fee of $5. Oh my, what can I say. The trail is NOT crushed limestone. At places it appeared to be an abandoned trail except for the path made by a bicycle tire. It was a muddy, sticky mess. I had checked ahead of time and found out the Stewart Tunnel was closed, which saved us back tracking since there wasn't a sign indicating the tunnel was closed. We detoured onto Tunnel Rd and took various paved roads into New Glarus. The best part of the trail was the Monroe WI segment. There was a detour off of the trail as we were coming into town. Very good signage directing us through the road construction area. There was a very nice trailhead with a drinking fountain and restrooms as you came into town from the north. We continued to the downtown area and decided to take a break and headed to the Dairy Queen by exiting the trail at 5th Street and riding to 8th Street. It was a challenge to cross the street but it was during lunch hour. As we headed out of Monroe there was an area of very loose gravel vs crushed limestone. An inexperienced rider might have wrecked. The rest of the trail was not maintained until it connected with the Jane Adams Trail. It was is good shape into Freeport IL.
