MARIN ULTRA CHALLENGE50 Mile & 50K
March 12, 2022
Marin Headlands & Mt. Tam
Congratulations Marin Ultra Challenge runners!
The Marin Ultra Challenge, our premier Marin County long distance trail race, delivers ample hills and sweeping descents. 2022 marks the 9th 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; 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.

50 MILE & 50K
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.

ADDITIONAL RACE INFO
Sunrise for Sausalito, CA: 6:31 AM
Sunset for Sausalito, CA: 6:12 PM
The vast majority of the course will be run on moderately technical dirt trails and non-technical fire roads. The hills can be long, and challenging! Hiking/trekking poles are permitted at this venue.
Courses are marked with colored surveyor ribbon, placed approximately every 200 meters along the course. Turns are marked heavily on the inside of the turn, with ~3 ribbons placed just before and just after the intersection. There will also be 8.5″ x 11″ laminated signs and flour arrows on the ground (when allowed) at critical or complicated sections. The detailed course map displays which colored ribbons must be followed for each route. Please keep in mind if you are running a longer distance, you will likely need to follow more than one color while out on the course. The most important course marking is the blue ribbon. Blue ribbons indicate “wrong way” trails. You will see blue ribbons, but do not run past a blue ribbon or you will be heading off course!
Drop Bags and Headlamps
Drop bags will be available at 2 different aid stations (which the 50 Mile will pass a total of 4 times, 50K runners will pass 2 times):
1) Tennessee Valley AS: Mile 10.5
2) Cardiac AS: Mile 19.8 (50 Mile Only)
3) Cardiac AS: Mile 29.3 (50 Mile Only)
4) Tennessee Valley AS: Mile 45.8
All drop bags must be left at the designated spot near the Finish line by 6:30 AM.
Drop bags will remain at each aid station until the aid station closes, unless they are placed by the “Return to Finish Area” sign, which will be available at both Tennessee Valley and Cardiac Hill. If bags are not placed by the “Return…” sign, they will NOT be returned to the finish area!
Runner crew is able to reach every aid station, but must abide by posted parking rules. There is no parking available at the Deer Park Aid Station. Crew must hike 1/2 miles to reach the Cardiac Aid Station.
Pacers may join runners at any time after their second pass through Cardiac Aid Station, mile 29.3.
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, Gu Stroop-Waffles, trail mix, pretzels, potato chips, Oreo cookies, Pop Tarts, PB&J sandwiches, M&M’s, Mike & Ike’s, boiled potatoes with salt, Coke, Mountain Dew, Ginger Ale, water, Tailwind Endurance Fuel, salt tablets, and seasonal fresh fruit. 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.
This a cupless event, meaning aid stations will not have paper cups available for runner use. Each runner will be responsible for carrying their own water bottle or reusable cup. Reusable cups are made of silicone, are collapsible, and easy to carry with you while you run. Going cupless will keep hundreds, or thousands, of paper cups from being thrown away or left littering the trails. Read more about our cupless events here. Reusable cups by HydraPak will be available for purchase at each event for $5.
Run with us at the MUC!
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.
To volunteer for this year’s event, please submit our online volunteer form.
★ In an effort to promote healthy competition, overall awards are determined by gun time (the first 3 men and women across the finish line). Age group awards are determined by chip time (the time from crossing the start line to crossing the finish line).

THE FINE PRINT
ITR Refund Policy:
Entry fees to our trail runs are non-refundable, and we do not offer transfers or deferrals to future races. Only registered runners can participate, and you may not exchange your entry with another individual. However, with advanced notice, we are happy to credit part of your entry fee to a future Inside Trail Racing event. A credit worth 50% of your original race fee will be issued if the cancellation is received at least 3 weeks prior to the race. There will be no credits or refunds provided if a cancellation is made within 3 weeks of the race. Credits will be available for 1 full year from its issue date. Only registered runners can participate, and you cannot exchange your entry with another runner.
Hosting a trail running event is an expensive and risky endeavor. All race costs are paid for well in advance of race day, so there is no financial gain to be made if a person does not show up on race day. We want all of our registered runners to show up, run, and have fun. While we understand that injuries, conflicts, emergencies, deaths, and other unfortunate events happen and may impact your plans for participation, we must adhere to our cancellation policies.
We do not cancel races due to rain or heat. Due to trail work, closures, or for myriad other reasons, permitting agencies may require changes to the publicized courses at any time prior to an event. This is out of our control, and we therefore will not offer refunds or credits in such a situation. If a race location is changed, but still hosted on the same day, we will automatically transfer the registration over to the new venue, or entrants may choose to run the race remotely and we will mail awards. If a race is postponed all entrants will be transferred to the new date.
If the situation does arise where ITR must outright cancel an event, for any reason, there will be no refunds. This could include earthquakes, floods, extreme weather, unsafe air quality, pandemics, or any other “Act of God”. There will be no refunds, but future race credit or deferrals may be available, dependent on the circumstances and how close to the race date the event was cancelled. We will communicate with all registered runners as soon as possible regarding the cancellation and any pertinent information.
Please refer to our online FAQ page for answers to other commonly asked questions.
