Each loop contains a couple of short stretches of pavement, primarily at the beginning and end, to help connect the different segments of the course. Runners will be treated to beautiful views of the Mighty Mississippi River from a number of stunning vantage points, a tour through and around the iconic
Horseshoe Bluff as well as panoramic vistas of beautiful grass prairies and dense hardwood forests. The trails range from steep & technical to flat dirt single track to rolling & grassy and everything in between. While there are plenty of hills to challenge you at the Mines, there are also ample stretches of trail where you can really open up and find your stride. This is a truly diverse course that is perfect for your 1st hundred or your 100th hundred!

Course Description
Welcome to the beautiful Mines of Spain, home of the 9th Annual 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 racecourse is a 25k out and back with approximately 2200 feet of elevation gain. The 50k runners will have the privilege of doing this twice with approximately 4400 feet of gain. 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.
