Route: Maroon Bells & Pyramid (CO)

You can do the peaks in any order.  Once underway, definitely stay on the trails or standard climbers routes. The other requirements:

1) start and finish at the Maroon Creek Trailhead; edge of the parking lot next to the bathroom. 

2) summit three peaks: Maroon Peak (14,156'), N. Maroon Peak (14,014'), and Pyramid Peak (14,018'). 

This Colorado 14er hat-trick has a mixture of runnable trail and technical terrain-particularly on the Bells Traverse-one of four "classic" 14er traverses in Colorado. Approximately 9,000' of vertical gain/loss and 12ish miles.

"Fells are what people in the north of England (especially in the Lake District ) call mountains and hills. Hence, fell running. Nothing to do with falling, but you may also do this a lot as the terrain is really rough and steep."

North Maroon only (8.9 miles / 4500 feet elevation gain):  Starting and ending at trailhead toilets by car park at the North end of Maroon Lake.  See https://www.14ers.com/route.php?route=nmar2&peak=North+Maroon+Peak 

The rock in these mountains is famously loose and rotten.  Please be especially careful not to kick rocks on those below you!

NOTE: Many Colorado 14ers should not be considered “backcountry” where you can go anywhere you want; their popularity can create a plethora of braided social paths that lasts for decades in the fragile tundra.  So if there is a trail, please stay on it!  Hundreds of volunteers work really hard to protect our beloved mountain environment (read here).
