325 Miles

Starting May 1, 2021, virtually travel 325 miles through Colorado. Solo or with a team!

The Challenge

This year’s Great Colorado Sign Challenge will virtually travel a mountainous 325 miles from New Mexico to Wyoming. Starting from the “Welcome to Colorful Colorado” sign on US-285 near Alamosa, we will travel north past Salida and Buena Vista before heading into Fairplay. Here, we will turn onto CO-9 and head over Hoosier Pass and into Breckenridge, Frisco and Silverthorne. When we reach Kremmling, we will turn onto US-40. Just before the summit of Rabbit Ears Pass, we will turn onto CO-14. Once through the small town of Walden we will make our final push along CO-125 to the finish line at the Wyoming border.

How many weeks will it take you to cover that distance? Take as long as you want, starting this summer. Do the Great Colorado Sign Challenge solo or with a team. This challenge should provide you an excellent test of fitness and a chance to plan to increase your training no matter how many miles you exercise weekly.

How It Works

Most importantly, have fun! You can use any form of non-motorized transport (running, walking, biking, swimming, SUP, Kayak, elliptical) anywhere you want, whenever you want. Go outside or on a treadmill or trainer. Average 3 miles a day or 10 miles a day – there are no set requirements. You can connect your trackable device to our online tracker to have your activities auto synced. You can also manually enter your mileage.
