14.1 miles according to my Garmin watch. 5 hours for me, trail running.

GPS clocked this at closer to 14 miles. I'm guessing it's because the app tried to have me go straight down the mountain where there was no trail. Hated coming down Shadow Canyon! First part is the best part, not too excited about the burned out area near Bear and S. Boulder Peaks. Not one I'm looking to repeat but good workout.

Couldn't summit Bear and SB peaks due to weather. Started by approaching Amphitheater Trail and up to Green Mountain. There are closures coming off of GM that redirect you through the newer Green Bear trail. This probably adds about an extra 1.5 miles. View the updated map. I hiked to the saddle and down through Shadow Canyon to avoid the storms that luckily stayed on the West side the remainder of the trip. This is a very long hike that will burn your legs on the way up and jerk your knees coming down either way you start. Awesome hike to get ready for 14ers.

This is an amazing but challenging hike . You'll experience several environments throughout the loop -- some more strenuous and others less so. Overall a great loop to get to some of the most beautiful peaks in Boulder!

Holy crap this is a tough trail. But it is totally worth it. The only reason I didn't give it 5 stars is that the Green Bear trail has been re-routed, which adds an extra 1 - 1.5 miles to the hike. Also, skip the flat part at the end and have two cars, if you can.
