The full loop is approximately 53 kilometers (33 miles) long. Komoot estimates the duration for gravel biking at around 3 hours and 34 minutes, but this can vary based on your pace and stops.
The trail primarily features wide and smooth crushed gravel, making it ideal for gravel bikes. You will also encounter some paved sections and roads. While mostly flat, there are a few gentle hills. Be aware that shaded areas might have snow or ice after precipitation, and the soft surface could be challenging for super-skinny tires.
Yes, this loop is generally considered easy and suitable for all rider levels, including beginners. It's largely flat with minimal elevation gain, and any small hills can be walked if needed. Komoot classifies it as a 'moderate gravel ride' requiring good fitness, but many find it very accessible.
