Marin Ultra Challenge - Sausalito, California - Running

The Marin Ultra Challenge is a Running race in Sausalito, California consisting of a Half Marathon Trail Run and 35K and 50 Miles (Ultra) and 50K Trail Run (Ultra).

The Marin Ultra Challenge, our premier Marin County long distance trail race, delivers ample hills and sweeping descents. 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.
