"Climbing Longs and its four buttress peaks in one day is a five-peak project that will stir sturdy souls" - Gerry Roach
"The route includes summiting Mt. Meeker, Longs Peak, Pagoda, Storm Mountain, and Mount Lady Washington. The route is around 17 miles long and 7500 ft of vertical gain. The route has a couple technical challenges with spots of low 5th class scrambling. The crux of the outing is getting from Longs to Pagoda, route-finding here is less straight forward and you can easily find yourself on steep terrain if you don’t descend correctly. The aesthetic of seeing a 360 degree perspective of Longs Peak throughout the day makes this loop a classic! " - Kyle Richardson
Roach's "Radical Slam" adds the relatively diminutive Battle Mtn and Estes Cone, plus requires 50 push ups!
