I rode the KRV from D Avenue to Galesburg and back on a recumbent bike. The most interesting parts of the trail are at the two ends. The trail undulates through wooded areas in both cases, but the D Avenue end is very hilly. The trail is asphalt throughout and mostly smooth. There are several highway crossings that require care. The part of the trail near downtown Kalamazoo has one underpass that is best traversed on foot due to sandy dirt on the trail. This section likely is unpassable after a heavy rain.

As the trail heads east there is a section that runs through a park along the river. But then the trail emerges onto a course along route 96 and heads into Comstock. The short ride through Comstock calls for care with turning traffic going into businesses. East of Comstock is a nice brief ride through a park before again returning to route 96. The final section of the trail is a very nice ride through a park into Galesburg.

I've been a user of the Fred Meijer M-21 trail since before it was restored to a trail. I've enjoyed walking, running, and biking it.

I would say for the most part, the route gets more and more intersting the further west you go. Though it's pretty neat running through the towns of Ovid, St. Johns, and Fowler, there isn't much inbetween other than cornfields. The west side of Ovid has some nice ponds and turns to the trail. However, you are a ways off the road M21, the paths surrounded by trees on both sides, and beyond that are more cornfields.

The scenery doesn't change much untill you hit Pewamo. From Pewamo to Saranac, the trail has numerous bridges over water and M21, some of which are very large and impressive. The trail is built above the river below, which makes for more to see and experience.

Unfortunatly, since many of these towns are distanced from each other, it's very likely you can go 7-8 miles without seeing anyone else on the trail. The only stretches paved are for a mile east and west out of each town. The soft gravel/sand is great for running, but will slow down mountain bikes, and be nearly impossible for bikes with skinny tires.

It would be great if it one day the whole thing was paved. I would love to see it exended further west to connect with trails in Ada and Grand Rapids. Another opportunity would be to extend it further east to Flint and those trails. Additionally, theres another opportunity to extend it north from St. Johns to Ithaca, to connect with the Highway 27 Trails.

Moved to Rockford because I wanted access to the White Pine Trail system. The trail is incredibly rough, especially for road bikes. The sections just north of Rockford after clearing the newly paved area are dangerous. I recently hit one bumpy series of ridges, and it instantly blew my front tire and I crashed. Additionally, the trail looks like a war zone with all the trees that have been uprooted and fallen across it from Rockford pretty much all the way up to Sand Lake. The windy conditions are not just a night time occurrence and it is just a matter of time before a tree falls and causes injury or worse to people during daytime hours when so many of us are on the trail. There needs to be a robust clearing of those trees that get uprooted so easily right on the trail. Finally, the ability to see at some of the road crossings is really limited and cyclists nearly have to get out into the roads before being able to see if cars are coming, and cars likely can't see the cyclists either because there is very little trimming of the heavy growth of vegetation. It's disappointing that a trail system that gets so much use, and that is one of the highlights that Rockford business people use as a selling point to attract residents, has not been maintained at a better level. I understand there are different townships the trail passes through, but the Rockford area (both north and south) is getting too rough and needs a great deal of work. There are rough spots all the way from 5/3 Stadium to Sand Lake that also need attention. What could be an outstanding trail has fallen into a state of disrepair in multiple places. Thank you.

I rode this very nice trail starting in Comstock Park going north. From there to Sand Lake, the trail is a very nice one to ride: gently uphill, some small towns, smooth asphalt, and spots to rest. However, north of Sand Lake, the trail turns from asphalt to a gravel two-track, and sometimes just a one-track. It is a rough ride that a road-biker would not enjoy. It's a shame that this part hasn't been improved since it is a Michigan State Park. That's why I only give it 3 stars.

This trail is very beautiful!! A lot of shade and some gorgeous scenery. Ends up in cannonsburg by the Honeycreek and Grist Mill, if you start at M44 & Myers Lake road. Grist Mill and Honeycreek Inn has some wonderful food!!

From Greenville to Edmore the trail is very bumpy. From Edmore to alma there are some bumps but much better. Mike M

Not every trail may be worth the time to ride, but this one is worth coming out and checking out for sure.

If you dare attempt the overlapping segment on Strava, note there are a lot of blind spots. Seems like an area ripe for an accident between a biker and someone taking a walk.

So enjoyable on a summer day. Very few people Monday AM during COVID. Just a few large cracks (that you’d experience on any trail like this in MI), but nice shade, scenery & up & downhills. Easy to follow without referring to a map. Hope to find a place for a beer & bite to eat, but didn’t explore the city this time. Nice people too - everyone says hello ¿¿

Rode from Lowell to Ionia and back, the trail is mostly crushed stone. Rode my Terra trike and average about 10 mph. Nice ride
