Location:  Maroon Bells Wilderness
Hike: Four Passes Loop
Distance: 26 Miles
Difficulty: Moderate


The awesome, jagged symmetry of the Maroon Bells, reflected in Maroon Lake, is perhaps Colorado's most often photographed mountain scene.  Climbers come in herds, despite the fact that these peaks are among the most difficult to scale in the state. Caution and skill are advised, but the rewards are stupendous. The Snowmass Creek Trail travels 16 miles to Maroon Lake and provides some of the best views of the Wilderness. In midsummer, the wildflowers are arguably the best anywhere. Although elk and deer still abound in the Elk Mountains, development around Aspen and Snowmass threatens their habitat.


The hike to Mount Audubon, one of Colorado's 13,000'+ peaks is seated in the vast Indian Peaks Wilderness.  This 6 mile round trip hike will take the group to the top of the continental divide with 360 degree views that include Longs Peak and Rocky Mountain National Park.

Our Front Range hike will be at lower elevation and meant to get your legs used to a couple consecutive days of climbing.  This will be pretty low impact and will probably only be for a couple hours.  Our afternoon will be freed up for a group activity in town.

The famous Four Pass Loop backpacking route in the Maroon Bells – Snowmass Wilderness is an international treasure.  This 26 mile (42 km) circuit climbs over four mountain passes higher than 12,000ft, past crystal clear alpine lakes and among the rugged beauty of the high Elk Range peaks.

Fine Print

Participants will be responsible for their own airfare and transportation to/from Denver International Airport (or elsewhere) to the designated hotel.  Prices are based on double occupancy.  Room assignments may be requested but cannot be guaranteed.  Participants must be in adaquate physical shape to carry a 40-50 lb backpack for up to 7 hours or 8 miles.  Participants will be responsible for carrying a portion of the meals in addition to their own gear and water.  Rental equipment will be offered at a later date for those who need it.

All participants will be required to bring all the items listed in the Mandatory/Required Gear List (available on the 'Files' tab)

Check-in, pre-race briefing, and start are all at the Mauthe Lake Recreation Area in the Kettle Moraine State Forest Northern Unit.

The race course follows the Ice Age National Scenic Trail through the entire distance of the forest. Racers will complete two out-and-backs. The first takes them to the Northern most point and back, followed by the Southern most point and back.

Gear is staged near the ranger station at the Mauthe Lake entrance.

Information not currently available

Are pacers allowed?

Pacers are allowed at any point during the race due to the increased level of safety they provide. They may not provide ANY support other than moral support. This is a self-supported event, not a pacer supported event.

How Do I Transfer a Bib?

The bib transfer process is now fully automated. The parties involved are solely responsible for payment transfer and confirmation. The process is as follows:

1. The recipient must have an account on the website
2. The current bib owner should log in and navigate to the event page.
3. The current bib owner will see an option to either view the 'want' list or 'transfer registration'

- Click on the 'View "Want" List' button
- Click 'transfer' under the Actions column

- Click on the 'Transfer Registration' button
- Enter the email address of the recipient (must be the one they registered with)

Upon completion, the registration will appear under the new users account. This can be verified by viewing the participant list.

Is there a medical check for participants?

There is no medical check during the event. The volunteers will do their best to keep an eye on the state of the participants, but are not expected to, nor qualified to make any medical judgements. It is the responsibility of the racers to access their condition and decide if they are able to continue. Race staff will have the right to pull any racer out if they feel they are a danger to themselves. All racers are required to carry a cellular phone to activate the 911 system if needed.

Can I stage gear or have a support crew?

Support is only allowed at the central staging area at Mauthe Lake. Participants may leave a drop bin/bag at the 46 mile Mauthe Lake checkpoint. Any spectators providing support beyond what is being provided by the volunteer staff to all racers will disqualify that racer.

What qualifies as the required shelter?

Starting in 2020, the extreme gear shelter requirement has been replaced by a 3-4 season bivy instead. This is due to the confusion surrounding what would qualify as a shelter as well as the safety concerns around being able to pitch a shelter in an emergency. Emergency bivys do not qualify. You may, however, carry the 3-4 season bivy as a replacement for the otherwise required emergency bivy when extreme weather gear is not required.
