“An epic day covering all four of Chicago Basin's challenging 14ers.”
— Tyler Prince
This run must be accessed via the Chicago Basin Trail, which is in turn accessed either by train (summer only) or by a long run in (Animas River Trail
While portions of this run can easily be explored by fit dogs, the peaks above it are generally too technical for them.
Camping high in the basin is generally frowned upon. See Twin Lakes Approach
for further information; camping along the end of Chicago Basin Trail is preferred.
This truly epic run summits all four Chicago Basin 14ers in one fell swoop. While seemingly short and with surprisingly little vertical, runners should know that all of these peaks are at least somewhat technical, and this day is sure to exhaust everyone short of Ueli Steck. Starting at camp, it takes runners up the Twin Lakes Approach
, up Sunlight and Windom
, back down and over to the Eolus Group
, and finally back down Twin Lakes Approach
. Between 14er finishers, completing all these mountains in one day is a big deal, and offers some pretty awesome bragging rights.

Need to Know
While similar in distance and elevation gain to many Sawatch 14ers or to 14er quadruple DeCaliBron, this run is a whole other beast.
This is a mixed bag of terrain, better for hiking fast than for truly running. Twin Lakes Approach
is absurdly steep and in some parts rocky, but largely runnable. Sunlight and Windom
are rocky and technical, and basically impossible to run. The Eolus Group
's lower trail is very runnable, for about 2 miles, before reaching the more technical upper portions. Overall, this isn't a bad trip for a runner who's open to some technical scrambling and slower hiking for much of the journey.
This is a hell of a trip. From camp off the Chicago Basin Trail:
Run up Twin Lakes Approach
. From here, it's recommended you summit Sunlight and Windom
first, as the rock on Sunlight is slightly more technical and prone to getting slippery. It's easier to escape from the Eolus Group
should the weather change later in the day.
So, run Sunlight and Windom
. Come back down to the Twin Lakes and run the Eolus Group
. From here, all that's left is a descent back down Twin Lakes Approach
Flora & Fauna
From world class alpine views and vegetation to unique alpine critters, Chicago Basin's got it all. Wildflowers down low are stunning. Marmots and pika are everywhere, and mountain goats love it up high, especially near Twin Lakes.
