All trails, paths, and roads are open to the public during the event. Use caution and common courtesy when encountering cars and other trail users!


The annual WEDU Aspen Fifty is entering its third year in 2018. The course remains similar to our 2017 event, but the start / finish is now at Koch Park near downtown Aspen. We are also adding a shorter 50K finishing option that returns you more directly to Koch Park 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 Koch Park near downtown Aspen (101 W. Cooper Ave.). Parking for the event is on the north side of town at the Aspen Music Festival parking lot, north of Gillespie St. between 3rd and 5th Streets. The neutral start will take Durant Ave. to left on Original Street, right on Neale Ave. ("No Problem" Bridge), right on King St., straight on Gibson Ave., left on Park Ave. The paved start of the big loop is over and racing is about to start!

Make a right 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. The race times and finish places will be taken at the bottom of Government Trail on Tiehack Rd. Ride the neutral finish back to Koch Park by crossing the Tiehack Bridge, make a left on to Moore Open Space trail, follow bikes paths to Marolt Open Space connector, and then follow more bike paths to a left on S. 7th Street, a right on Hopkins Ave., and a right onto Midland Trail to return to the finish area. Please note that racing on this final neutral part of the route could affect future versions of this event. Please use these final miles as a cool down and yield to other trail users.
