The Marin Ultra Challenge, our premier Marin County long distance trail race, delivers ample hills and sweeping descents. March 10th marks the 7th 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 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 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 the ultimate trail runner’s destination.

Starting at Fort Cronkhite and Rodeo Beach, runners may fill their lungs with fresh salt air before embarking on a journey through some of the best trails the Marin Headlands and Mt. Tamalpais has to offer. Your journey will begins with amazing vistas of San Francisco and the Golden Gate Bridge from the SCA and Julian trails. You’ll soak in the beautiful views of Coastal Trail, the inland buffed single track of the Miwok, descend on the famous Dipsea Trail and tackle one of the toughest climbs around – Willow Camp. You’ll travel along the coast, by Pirate’s Cove, to Muir Beach. Fron there you will cross over to Mt. Tam, climbing to the top of Cardiac Hill then scream down the Dipsea to Stinson Beach. Depart Stinson Beach with the 1,800′ of vertical gain in 1.8 miles on Willow Camp and traverse Mt. Tam along the single-track Coastal Trail, back to the top of Cardiac. Enjoy the tall trees as you pass through Muir Woods, before you climb back into the Headlands on Miwok to the killer downhill of Dias Ridge back to Muir Beach. From there, you’ll quietly pass through the Zen center and up the incredible new Middle Green Gulch hill then traverse through the Headlands all the way back to the finish at Rodeo Beach.

Inside Trail Racing aid stations are replete with an optimal variety of glycogen-replenishing, electrolyte-replacing products. The following is a list of some of the foods and beverages each aid station may provide: Gu Energy gels and chews, all-natural nutrition bars from Larabar, trail mix, pretzels, potato chips, Oreo cookies, Pop Tarts, boiled potatoes with salt, Coke, Mountain Dew, Ginger Ale, water, Tailwind Endurance Fuel, PB&J sandwiches, M&M’s, Mike & Ike’s, salt tablets, and tangerines. Aid stations are also equipped with general first aid items but no anti-inflammatory medicine. As distances between aid station vary, we strongly encourage all runners to carry at least one 20oz bottle during their run.
Tailwind is mixed so that it contains 180 – 200 calories per 20 fluid ounces.
Without the support of enthusiastic and caring volunteers producing our races would not be possible. Volunteers of all ages and abilities help with setup, check-in, aid stations, course marshaling, timing, and post-race food.
Volunteering is a fun, novel way to experience races, play in the outdoors, and spend time with friendly people. All volunteers receive a free race T-shirt, free food, and the ability to earn credit toward a future Inside Trail Racing event, commensurate to the amount of time worked. Five hours of assisting an event results in a free race credit or Inside Trail merchandise.
