The annual WEDU Aspen Fifty is entering its third year in 2018. The course remains the same as our 2017 event, but we are now adding a shorter 50K finishing option that returns you to Buttermilk after passing through the Woody Creek area.

You'll enjoy a combination of new and classic singletrack, fast doubletrack, and smooth paved paths as you take a grand tour of the Aspen/Snowmass area. If you're lucky enough to score a spot in this event, thanks for supporting the Roaring Fork Mountain Bike Association! RFMBA's mission is to create and sustain the best possible mountain bike trails and experiences in the Roaring Fork Valley and beyond. We couldn't do it without ongoing support from our members, sponsors, and public land manager partners!

Need to Know

This event is organized for Sept. 15th, 2018, stay tuned for all details. Please respect all land manager trail regulations while on White River National Forest, Pitkin County Open Space and Trails, City of Aspen and Town of Snowmass Village Trails.


This course is a large loop that starts and ends at and near the Buttermilk Ski Area Parking Lot. Start by crossing Highway 82 to get on the Bike Path between Aspen Airport Business Center & Aspen, heading into Aspen. The next part sounds complicated, but you'll be with the neutral start 'peloton' so it should be easy to not get lost.

Make a left onto Cemetery Lane, and then an immediate right onto Power Plant Road, which turns right onto W. Smuggler Road. You are now cruising through Aspen's West End residential area. Make a right onto N. 1st. St., a block later turn left onto W. Francis St. and a block later turn left / straight onto the short bike path behind the Aspen Post Office. Negotiate the parking lot to turn right onto Puppy Smith St. Make a left onto N. Mill St. followed by a quick right onto Gibson Ave. Gibson flows onto South Ave. and then Park Circle. The paved path and road start of this big loop is finally over!

Make a left onto Smuggler Mountain Rd., you're now on dirt and the first real climb, time to let the big effort begin!

Make a left onto Hunter Creek Cutoff, followed by a right onto Iowa Shaft Trail. Make a right onto Hunter Valley South, cross the bridge, and turn right onto the Hunter Creek Trail. Turn left to start the climb up Hummingbird Trail.

At top of Hummingbird, turn right onto Red Mountain Rd. Make a right onto FS Rd. 130, and then a short while later, another right onto Hunter Creek (Overlook) Trail. Make a left onto FS Rd. 130 - upper section, soon enough you'll top off at Van Horn Park - a good place to take a breather and enjoy the big views if you're in the mood.

From the top of Van Horn Park, turn right onto FS Rd. 131. Then a short few yards later, turn left onto the Hobbit Trail. It's a steep climb followed by a fast and flowing and mostly downhill section to the Four Corners junction. At end of Hobbit, make a right onto Tinpot, which is a big descent to the town of Lenado, where you'll make a left onto Woody Creek Road. You'll find aid station #1 in this area.

You're now on a big road descent, first dirt, then pavement, down to Woody Creek. At the road's end, make a VERY sharp left, almost a 180-degree left turn, onto Upper River Road. Pedal past the Woody Creek Tavern, make a brief right onto Smith Hill Way, and then a quick left onto the Aspen Mass bike path, which climbs up to the Intercept Lot.

From Intercept Lot, climb up Brush Creek Bike Path to the Snowmass Recreation Center (aka Town Park, aka Rodeo Lot), which you'll skirt around using Brush Creek Rd. and Horse Ranch Rd. for a short distance. Follow signs to the Rim Trail, which you'll ride for many miles, all the way to Divide Road. Turn left on Divide Road, and then a sharp right onto Brush Creek Road. Follow this winding road until it starts going down steeply, then make a right on Daly Lane. For reference, Daly Lane is parallel to and below the Snowmass Village Mall. Follow signs to Tom Blake Ridge Trail, which leads you to climb to the right onto the paved Wood Road.

Climb the paved Wood Road till it tops out (where it is briefly named Pine Lane), and make a left onto the dirt Elk Camp Work Road. After a bit of descent and some fast flat, this dirt road climbs up to the start of the Government Trail.

Make a left onto Government Trail, which will bring you all the way back to Buttermilk. A left onto Oregon Trail for a brief climb and then a right on the Buttermilk Mountain Summer Work Road will drop you back down to the start/finish area. Be sure to keep your bike upright in the closing half mile as you'll have loose rock, tight turns, and plenty of high speed on doubletrack dirt and rock roads leading to the finish line.
