The second leg of The 50/50 ChallengeThe Marin Ultra Challenge, our premier Marin County long distance trail race, delivers ample hills and sweeping descents. 2026 marks the 13th edition of this tour of some of Marin’s best trails (we lost a couple years due to the pandemic). Meticulous effort went into the design of each course for the MUC; both distances are physically demanding (the 50 Mile has just about 11,000 feet of elevation gain) and exceptionally beautiful. The journey begins at the black sands of Rodeo Beach, and 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 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 the ultimate trail runner’s destination.
