Mt. Evans Ascent

Idaho Springs

Although the air will be noticeably thin at the starting line, Echo Lake’s 10,600 feet of elevation is just the beginning. The climb totals nearly 4,000 vertical feet – much of it above treeline – as you make your way 14.5 miles to the finish line located at the summit of one of the most recognizable peaks on Denver’s mountain skyline – 14,264 foot Mt. Evans.

Be inspired!!!

Join us on June 8, 2019 for another memorable run.
Spectators will include Bighorn Sheep, Marmots, and Mountain Goats – maybe even a few people!!!
