Welcome to the beautiful Mines of Spain, home of the inaugural Miner 49er endurance runs. On the course you will run on lots of single track, some double, and even some prairie trail. You will have views of the historic Julien Dubuque Monument, the very popular Horseshoe Bluff, and the beautiful Mississippi River. The race course is a 25k out and back with approximately 4,400 feet of elevation change. The 50k runners will have the privilege of doing this twice with just under 9,000 feet of change. You will be challenged by stone steps, stream crossings, and the usual rocks and roots that can trip you up without notice. The course will have three aid stations that will be stocked with all the usual "ultra event" nutrition. Since, this is being held in a public park there may be non-race traffic out on the trails and in the area. Be respectful and give them a friendly wave as you pass by.
