This route was planned by komoot.
The full loop, which is about 17.1 kilometers (10.6 miles), generally takes around 4 hours and 29 minutes to hike at a steady pace. This duration can vary based on your fitness level and how often you stop to enjoy the surroundings.
The Carl Henn Millennium Trail is entirely paved, offering a smooth surface suitable for hiking, running, and cycling. While it's mostly flat, expect a series of gentle long hills and valleys, with notable inclines between the 0.5-mile and 2.0-mile markers on West Gude, and again from the 7.5-mile to 9.0-mile markers on Wooton Parkway. There's also a final significant climb in the last mile if you're heading back towards the Thomas Farm Community Center.
While komoot rates it as 'moderate' for hiking due to its length and some undulating sections, many consider it accessible for most fitness levels. The paved surface and gentle hills make it manageable for beginners, though the full 10-11 mile loop can be a good workout. It's a great option for those looking to build endurance.
The trail offers a diverse mix of urban and suburban landscapes. You'll pass through residential neighborhoods, commercial areas with shops and restaurants, and various parks. Some sections provide quieter, more forested areas, while others run alongside busier roads and even an industrial area on East Gude Drive. This variety means you'll experience both the convenience of city life and patches of natural beauty.
