Event Description

The Marin Ultra Challenge, our premier Marin County long distance trail race, delivers ample hills and sweeping descents. March 14th marks the 4th edition of this tour of some of Marin?s best trails. Meticulous effort went into the design of each course for the MUC; all three distances are physically demanding (the 50 Mile has just about 11,000 feet of elevation gain) and exceptionally beautiful. The journey begins underneath the Golden Gate Bridge, then traverses the Marin Headlands, Stinson-facing Mt. Tamalpais and Muir Woods, exhibiting a range of terrain, from exposed fire-roads with incredible coastal and inland views to tight, technical single-track with redwood canopies. There is very little trail overlap, and Jim Vernon, from The Endurables and Hydrapak, spent hours and weekends developing these spectacular custom courses?we are super excited to show it off. You?ll quickly realize why Marin County has become a trail runner?s destination. Since this is one of our favorite and most challenging events, we are offering a good little chunk of prize money in the 50 mile race!! Male/Female 1st-$300, 2nd-$200, 3rd-$100. In addition, we will have special awards for the 25K and 50K distances and each age group. Don?t miss this grand tour of the ultra-running mecca, Marin County, California.
