Leave No Trace Principles

“Take only photos. Leave only footprints.” It’s a phrase we’ve all heard before, but how and when does it apply to our outdoor adventures? All challengers are required to follow Leave No Trace principles.

Plan Ahead and Prepare
Know the regulations for the trail. Prepare for weather and other emergencies.
Travel and Camp on Durable Surfaces
Stay on the trail. Walk in the middle of the trail, even when muddy or wet.
Dispose of Waste Properly
Pack it in, pack it out. Yes, that includes your toilet paper.
Leave What You Find
Don't collect plants, flowers, or rocks. Leave nature as you find it.
Minimize Campfire Impacts
Only an issue in areas that allow campfires, and typically not an issue for day hikes. Make sure that fire is completely dead.
Respect Wildlife
Don't approach or feed wild animals. Control your pets and store food separately.
Be Considerate of Others
Respect others on the trail. Take breaks away from the trail. Enjoy the sounds of nature and avoid loud noise (like Bluetooth speakers).

Hiking Groups

The Six-Pack of Peaks Challenge can be hiked solo, with friends, or with a group. Group hikes can be a great way to meet others and explore new trails together.

Why hike with a group?
Solo hikes can offer solitude and peace, but group hikes can be a great way to experience the challenge. Check out our guide to finding others to hike with.

Training for the Challenge

Successfully completing the challenge requires preparing physically and mentally before even tackling your first peak.

Hiking Training One of the best was to train for the challenge is by hiking. Start with shorter distances, and work your way up to the distances you'll be hiking in the challenge. Once you have the distance, add-in vertical gain. This can be accomplished by multiple climbs, or a roller-coaster style hike. Plan to hike 2-3 times per week, with one longer hike each week.
Strength Training In addition to hiking, strength training can improve your durability and resilience for the challenge.
12-Weeks to Hike Fit program includes hiking and strength training. Developed by Lee “Flick: Welton of Trailside Fitness, Certified Personal Trainer and PCT thru-hiker.
