SUMMIT COUNTY — If Barney Flow is a mellow taste of mountain biking’s wild side, then neighboring B-Line is cranking it up to 11.

Found nearly side by side above Carter Park, the two skills trails were built with progression in mind: small rollers, berms and rail bridges on Barney Flow, followed by medium-to-large features and drops on B-Line. Both are short and sweet, but B-Line is a touch longer at about 0.75 miles from start to finish, with more vertical drop to help riders pick up speed for the bigger bridges and jumps.

Question is: Does pumping the adrenaline to 11 mean you need a full downhill or enduro bike to ride B-Line? Not quite, but like the trails at Keystone Bike Park, these features are more enjoyable (and safer) with a full-suspension model. The full-face helmet and shoulder pads are up to you, but surely Spinal Tap would approve.

To reach B-Line, pedal uphill a few hundred yards from the mud meter at the start of Barney Flow. It’s on the Breckenridge side of County Road 503 — if you’re on Barney Ford Trail, you’re on the wrong side of the road.

B-Line begins with three bridge options ranging from small to large, including a skinny rail bridge with a four-foot drop on the far right-hand side of the trail. Every feature on the skills track is marked with symbols like ski runs (blue for intermediate, black for advanced). Once you’ve picked a line in this early section, stick to it, and remember the trail is uphill only.

These three early options lead to one of two lines: a berm turn into meandering rail bridges and more berms on flatter ground, or a gap jump over the first berm into a set of graduated tabletop jumps on steeper terrain.

From here, continue riding your line as it leads to even more rail bridges, including a spider-like contraption with three route options and a gap jump off rails hardly wider than your wheels. Follow these to the final stretch of jump and drop options before a screaming descent through big berms to the connector trail above Carter Park. Merge onto Moonstone Trail for the uphill and another lap.


Parking is available at Carter Park. From the intersection of Main and French streets in Breckenridge, head south on Main and make a left onto East Adams Avenue. Follow the street a few blocks, then take a right onto South High Street (a T-intersection). Follow High Street until it dead-ends in the Carter Park parking lot. Follow the Carter Park switchbacks roughly 0.5 miles to Moonstone Trail. Take Moonstone another 0.5 miles to County Road 503, then cross the road to access B-Line and Barney Flow.
