5 stars as a climb. The day after the copper triangle this was the easiest way up to the good stuff and very manageable. Would be a 3 star descent, you could really fly but it wouldn't be that interesting.

A fairly mellow climb on an old
Forest road. Great way to gain elevation.

its fan to ride it starting from the mountain, but you can do it also from the bottom in Breckenridge. half of the route is with melting ice or really wet or even still with snow. but aside of that is fan and at the end when you are getting into Breckenridge flows pretty well. there are really sharp curves at the end.

It is a great climb, and not steep other than two very short pitches near the top. Great connector to fall classic

This is generally a downhill trail. While it's technically a 2-way trail, biking up slalom is generally frowned upon unless it's for a comp. The preferred route up is Upper Flume to Gold Run Gulch Rd.

s/o to the Breck trail crew for clearing that thing off right before I rode it. Super fun trail!

Who wouldn't like bike optimized, downhill only berms, turns and jumps? Really well done, super fun. Main line rollable but lots of opportunities for bigger air and doubles.

just rode the trail. It was re built. It now features tabletop jumps, hips, wooden features and it’s now downhill only. 10/10 would recommend riding up backdoor and down sidedoor

Back door trail is now preferred way up to ride Side Door down. Back Door doesn’t show up yet on Trailforks map.

A flow trail that did not exactly meet expectation. Its a shame as it could have been a great trail, but there are alot of grade reversals that kill your speed and flow.

It was just rebuilt last summer. Try it again. Hands down one of the best non-park DH trails in Colorado, now.
