Cotopaxi (19347' / 5897m) is the second highest peak in Ecuador.

Up & down from Ingreso norte al Parque Nacional Cotopaxi:  (35 km, 2172m ascent)

Charles Raffensperger proposed the challenge (2/16/2015):

Modeled after the South Beyond 6000 (SB6K) I'm planning a similar challenge in Georgia to climb all 4000 or higher peaks in one continuous footpath starting April 3, 2015. There are 32 named peaks along with 3 other "provisional" peaks - I plan to climb all 35. I'll be taking a west-east route and expect the total route will be slightly over 200 miles. To-date there appear to only be 2 other people who have climbed all of these peaks, although not in one continuous trek.

Kings Peak (13,528') lies deep in the Uinta Range and is the highest summit in Utah. There are several trailheads to access Kings, but the shortest and most commonly used approach is from the Henry's Fork TH. Even this route requires a 25-mile round trip with 4000' of vertical gain (and loss).
