The Migizi Loop is a paved trail around Pike Bay near the town of Cass Lake in northern Minnesota. Migizi is the Ojibwe (Chippewa) word for bald eagle. The Migizi trail system is mostly contained inside Chippewa National Forest, with a small section of trail running through the town of Cass Lake. Pike Bay is part of the larger Cass Lake on the Mississippi River, a popular resort and boating area in the summer. The Migizi trail system has a small sidetrail leading to Norway Beach that is not part of the Migizi Loop.

In Lake Vänern's archipelago, just outside Mariestad, you will find lonely and beautiful Brommö Island. Here on the almost completely car-free island is the 14-kilometer-long hiking trail Brommöleden. Run in a nature reminiscent of the Swedish west coast - with dunes, cliffs, beaches and clear blue water.

The trail is signposted excellent with orange markings. It follows forest roads and smooth, wide paths.

The Dartmoor National Park covers 368 square miles, and there are many options for running in that area. One option is to run all the way across, and an obvious way to do that is using the Two Moors Way (https://twomoorsway.org/about-the-route/). The TMW goes from Ivybridge to Lynmouth, passing through Exmoor and Dartmoor, and this route is the section that is included within the Dartmoor National Park, a 36 miles route.
