This trail is not the best for road cycling. Though it covers over 70 miles from Hinckley, MN to Duluth, MN, it consists many "bumps". Cracks, and some rough sections.
This trail is very safe because there is absolutely no vehicle traffic. There are some minor pedestrian traffic and some other riders at time.
The amenities on the trail are great. There are spots to camp over night, restrooms, plenty of benches to sit on to rest for a quick snack break as well as small towns on the route to stop over for lunch or a longer break.
