Inaugural event benefiting RFMBA that takes in the best of Hunter Creek, Sky Mt. Park, and Snowmass.

Mike Pritchard

Overview [Suggest Changes]

While this inaugural ride is not actually a race, you can expect some truly fast riders to be leading the way as soon as the pedaling starts.

The course may change somewhat on the day of the event, including start/finish area, so be sure to listen up to last minute changes and be on the lookout for course markings at trail and road intersections. Volunteer course marshals are expected to be located at many road intersections, but please be aware that no road closures are expected during this event.

After climbing Smuggler Mountain Rd., you'll enjoy classic and modern trails on your way up to the first high point above Hunter Creek, Four Corners. After a fast singletrack descent to the little town of Lenado, you'll hit dirt and then paved roads on a big descent to Woody Creek.

Continuing on paved roads and paths for a while longer, you'll finally hit singletrack again, which mostly won't let up until it's all over. You'll visit the singletrack trails of Sky Mt. Park before taking in a big loop of Snowmass using the Tom Blake and Rim Trail.

After a final downhill bike path segment, it's one more singletrack climb, and then a final descent on Airline Trail down towards the start/finish area.
Features: -none- [Add/Remove]

Description [Suggest Changes]

Pre-registered participants will be given more instruction at the start/finish area about the route that the event will take to start out the ride. Turn-by-turn instructions start when the course hits the dirt at:

Smuggler Mountain Rd., where you'll climb up to the observation deck and make a left onto Hunter Creek Cutoff. Follow until it's time to go straight / right onto Iowa Shaft Trail.Make a right onto Hunter Valley South, then cross the upper bridge and make a right onto the Hunter Creek Trail. Follow this valley floor trail for about a half-mile and then make a left onto Hummingbird Trail.

At the top, make a right onto Red Mountain Rd. and keep climbing until the fork in the road. Make a left here on the Four Corners Road. At the top of this road, go straight onto Tinpot (aka Tincup), this takes you all the way down to Lenado where you'll make a left onto the dirt Woody Creek Road and head downhill.

Woody Creek Road eventually turns to pavement and finally meets Lower River Road where you'll make a super sharp left hand turn to start heading up-valley. In a short distance, you'll pass by the Woody Creek Tavern. Keep going! Make a right on Smith Way, crossing a paved bridge over the Roaring Fork River. At this point, make a hard left onto the Aspen Mass paved bike path, which will climb you up to the Intercept Lot.

Once at the Intercept Lot, it's time to climb Cozyline Trail to Skyline Ridge Trail, where you'll traverse Sky Mt. Park until it's time to drop down Deadline Trail. Use true caution if you've never descended this trail since it includes man-made jumps and big sweeping bermed turns.

At Deadline's end, make a left onto Highline trail, and ride it until it crosses Owl Creek Road to meet with the Tom Blake Trail. Ride Tom Blake all the way to Fanny Hill, adjacent to the Snowmass Village Mall. The course will go straight onto Daly Lane, which is the road parallel and downill to the pedestrian Village Mall. At end of Daly Lane make a left onto Brush Creek Road, up steeply for 30 yards, then follow the road right, left and then downhill on a long sweeping U turn until it's time to make a hard left onto Divide Road.

A short distance later on Divide Road, look to your right for the trailhead of the Rim Trai, This trail is a combination of big climbs and big descents on your way to the Snowmass Recreation Center (aka Town Park, aka Rodeo Lot). If you've made it this far, it's time to drop down the paved Brush Creek Bike Path and make your second climb up Cozyline Trail.

This time, instead of climbing up to the ridge, you'll make a left onto the Airline Trail, dropping all the way down to the Owl Creek Trail. After just a few hundred yards on this paved path, make a hard right, cross Owl Creek Rd. to gain the final singletrack segment, Buttermilk Connector, which will get you back to the parking lot at the base of Buttermilk Mt. Ski Area.
