Colorado boasts 58 mountain peaks reaching over 14,000 feet tall. To locals, these high-rising peaks are well known as "fourteeners" or "14ers."

Hiking any of these peaks can be a great challenge (and not entirely family-friendly), so we're encouraging our community to get outside and complete a 14er hike on a FLAT surface. We're making it simple with a free printable chart that shows the flat distance it would take to hike a route on each of the 58 famous peaks.

“Happiness is not at the top of the mountains but in how to climb it.” - Unknown

Here's how our Flat 14er Challenge works:

• Print your Flat 14er Challenge checklists.
• Pick a peak.
• Start walking, running, jogging, biking, etc.
• For each mile you travel, fill in a triangle on the chart.
• Celebrate your success!
• Start the process over again for as many peaks as you'd like to hike.

You don't have to complete the roundtrip journey in a single go. Complete this challenge at your own pace, on your own time.
