The Porcupine Mountains are one of the largest tracts of wilderness east of the Mississippi River. The Porcupine Mts overlook Lake Superior, the largest fresh water lake on Earth. The coastline is remote and rugged. The Porcupine Mountains Trail Marathon course includes some of the most remarkable single track in the midwest and takes runners past tranquil and remote Mirror Lake and along the classic Escarpment Trail where you can almost reach out and touch soaring hawks as you overlook Lake of the Clouds. This event completes a trio of deeply inspiring trail marathon hosted by Great Lakes Endurance (Waugoshance, Grand Island, and Porcupine Mtns) offering runners the best of what Michigan and the Upper Great Lakes have to offer.
