The MLBFL is 53 miles long and roughly 5,500 of climbing. It encompasses pretty much everything Mammoth is known for: Tree-lined singletrack, soft pumice runs, fast descents, gorgeous traverses, demanding climbs, and amazing views. If you want to ride pretty much ALL THE BEST cross country trails in Mammoth with one shot, this is the ride.
This is a grassroots, unofficial ride/race created by Fat Bike Mammoth (local MTB club). There is a grand depart each year, or you can ride it as an ITT (individual Time Trial). Finishers and times are recorded for bragging rights only. Grand Depart date, cue sheets, gpx files, and more info at: fatbikemammoth.com
We highly recommend using gps, as this route will be hard to navigate without one (especially the Shady Rest Park portion). Definitely keep cue sheets with you. Also a good idea to grab a Mammoth Mountain Bike Park Map and a USFS map and/or one of the local guide books.
Carry plenty of water, food, and/or cache some stuff. It's a long, tough ride.
In a nutshell: Start off of Forest Trail Rd (behind the Fire Station). Ride singletrack and doubletrack through Shady Rest Park, including trails from various VC courses (local xc race series). After climbing out of Shady Rest Park, you continue climbing singletrack on the Uptown Trail
into the Mammoth Mountain Bike Park.
Jump on Brake Through
to Lincoln Express
. This area offers up great views to the town below, as you traverse Lincoln Mountain. Finally you get some relief from climbing as you descend Lower Skid Marks
and get some more fast, flowy riding on Manzanita
before reconnecting with Uptown Trail
. Continue up to Main Lodge and climb Beach Cruiser
to Mountain View
After leaving the bike park, climb up to Minaret Vista for outstanding views of Mammoth Mountain and The Minarets. Take a breather, because next up is the steep climb up the San Joaquin Ridge Trail
(locally known as Hard Core Trail). This is an out and back section that takes you to the Wilderness Border and the high point of the route. Fly down the descent, and connect with Mountain View Trail
. Ride to the Earthquake Fault, and re-enter the bike park on Uptown Trail
for a short jaunt. Yes, you're re-tracing a short portion of this trail. After a short climb, cross over to the Downtown Trail
and connect to Big Ring
. Climb to Paper Route
and ride past the Twin Lakes Overlook where youclimb to the intersection of Skid Marks
. Turn around and ride back down Paper Route
to Lakes Trail
. Some excellent views from this exposed trail that drops you in the Lakes Basin.
Cross Lake Mary Rd. and jump onto the Panorama Dome Trail Mountain Bike . Descend some more sweet singletrack on Mammoth Rock. Take Sherwin Creek Rd to Old Mammoth Rd and connect with the Town Bike Path. Ride near Mammoth Creek Rd and loop around toward Shady Rest Park, ending where you began. An epic adventure that covers the best Mammoth has to offer in a one-day ride youll not soon forget!
This route was created in 2013 by Fat Bike Mammoth in the vein of other self-supported, grassroots endurance events with similar namesake. Check out the Sedona Big Friggin Loop, Santa Fe Big Friggin Loop, Salida Big Friggin Loop, etc.
