This is my favorite place to run! It’s also great for biking or walking. There is a mix of hills and flat land. It gets hilly going south to Crystal Lake and north to Richmond, but it’s pretty flat through all of McHenry. This is a 28-mile trail that goes from Genoa City, WI to Algonquin, IL. It also connects to other paths, including one that circles all the way around northern Illinois. It is beautifully maintained. I love that it goes through so many different towns; it makes for a lot of good scenery! I love to run through my hometown, McHenry, at sunset, because the path passes Petersen Park beach and gives you the perfect view of a beautiful sky over the water. I love that this trail exists near me!
