"The paved road on Mount Evans ends as the highest in the northwestern hemisphere and is one of the most unique rides in the World. One of the most difficult climbs in Colorado, it is not steep but its length and altitude will work on many riders all the way up to its craggy summit. The start is a bit congested and over shallow grade but signs of civilization soon end and the grade gradually increases along a tree lined route within a drainage. Graceful curves and a very steady grade accompany you on this stretch. As you approach Echo Lake the grade eases and then goes flat for a short section as you pass the lake on the right..." (This quote is presented with the approval of John Summerson, from his book, The Complete Guide to Climbing (by Bike) in Colorado, pg. 100.)
Climbing Mt. Evans is all about altitude, not gradient.  The grade is almost always in the 4-7% range.  45% of the climb (12.4 miles) is at 0-5% grade and 47% (12.7 miles)  5-10%.  The steepest quarter mile is only 8.4% and the steepest mile 6.6%.  I've ridden Mount Evans four times and do not recall ever seeing a double digit grade on my Garmin.  The average grade is a mild 4.5% (5.8% if several brief descents are removed from the equation).  

See more details and tools regarding this climb's grade via the “Profile Tool” button.
Roadway:  The roadway is in excellent condition although beware of the expansion joints (linear ruts) in the road along much of the upper section of the climb -- they are very uncomfortable.  

Traffic:  Mild and not a problem.  

Parking:  There is ample public parking at the climb start. Map, Street View. 
The only place to get food and liquids is the Echo Lake Lodge at mile 13 (Google Map + Reviews).  As for clothing, check the PJAMM weather tool for Peak Weather and bring warm clothing as indicated by the summit weather forecast.  Remember, you are starting your climb nearly 7,000' above where you start. 
Before heading out on any cycling adventure check out our Things to Bring on a Cycling Trip and use our interactive check list to ensure you don't forget anything.
At the Top:  Check out the views at the parking lot and sun dial area. Also consider walking a short distance to the Welcome Center near the lot and Meyer Womble Observatory (Google Map + Reviews; the observatory is not open but the hike and views are great).  Also consider hiking to the very summit (4350m/14,271') which is a 0.3 mile hike gaining 80' (map).  See All Trails Best trails in Mount Evans Wilderness if you are interested in hiking. 

Accommodations: We have stayed in Idaho Springs (where the climb begins) for our four climbs up Mount Evans. You would not go wrong by staying in Denver (30 miles) or Boulder (44 miles) from start of the climb, as both locations are great places to stage a cycling trip.  All of these locations have private vacation rental options. See the Denver Climb Page and Boulder Climb Page for more info.

I just signed up to say thank you for providing the detailed information on this ride as well as Pikes Peak. I flew in from Korea last weekend for this ride and was able to make it up the mountain. The goal for me was making it up safely rather than breaking any records. It is indeed a strenuous climb going through multiple temperature and air pressure zones. A couple points: riding in August you can easily ride with a short sleeve jersey and short bibs for the first 3/4 but you should have a windbreaker or kneewarmers/armwarmers for when you get to the top and for when you get back down. I also recommend full finger gloves. You can easily stock up on drinks/energy at the halfway summit house but after that there is really nothing so bring at least two large water bottles and plenty of energy bars or boost ups. After 2pm it starts to get real chilly on top so plan on reaching the top before then. As noted in the article, there is plenty of parking at the bottom at the ranger h

I rode this on 8/2/21 and this truly embodies an epic climb from start to finish. Road quality: great from the start to Echo Lake, less than average from Echo to Summit Lake, awful from Summit lake to the top. There is a toll booth at Echo Lake, but no toll for bikes. Cars that want to go from Echo on the road to the top require a reservation in addition to the toll. Plan accordingly if you want to drive on the road or have a support car. I did Mt. Lemmon, Mt. Mitchell, and Dante's View prior to this so I had a good idea of how to approach the climb. The altitude was the only thing I had no experience with. It affected me mentally, I found that after Summit Lake I became scatterbrained and woozy. But I was aware it was happening to me so I knew not to panic. I wore a windjacket the entire ride. It is a must have here. The temperature at the top was in the 40s. Descent was slow due to road quality, disc brakes are a must. DEFINITELY DO THIS CLIMB!

One of my favorites. Start from Idaho Springs and be sure to take off early in the morning. Otherwise, you risk running into afternoon thunderstorms and significantly more traffic. Until arriving at Echo Lake, the road is awesome. Above Echo Lake, expect some seriously rude road surfaces. Incidentally, while most address the mountain CLIMB, the decent below Echo Lake is absolutely awesome!

I biked this last summer when it was closed to cars (all summer!) Was very glad to have zero traffic. The road close to the summit is pretty jarring. Large seams in the road make the descent a little scary at times. But besides that the conditions are pretty good. There are always mountain goats at the summit and a nice area to snack and rest before descending. I started in Idaho Springs, which makes the round trip 55 miles with about 7,000 feet of climbing.

The first half from Idaho springs is pristine road but heavier traffic. In Sept of 2020, the road was closed to traffic from echo lake to the summit. So zero concern of vehicles. However, the road from echo lake to the summit is deteriorating pretty rapidly. Very rough descent. A must do climb simply to say you’ve done the highest rd in N.A. - MUCH easier climb than Pikes Peak.

In my few short years on the bike, this has been my favorite ride to date. The highest paved road in North America at over 14,000ft is breathtaking. One, because of the altitude, and two because of the amazing views. We were lucky to get a clear day in July with cool sights like 7+ feet snow drift and numerous mountain goats. I enjoyed this one more than it's fellow Colorado 14'er, Pikes Peak, as the grade was less extreme and less traffic. Traffic the first half from Idaho Springs was moderate, but once turning at Echo Lake it was less. The few cars that did head that way were even cheering us on along the way. Be sure to take some time at the top to soak in the views. Be careful the first 5 or so miles of the descent as the road was quite bumpy when I did this ride in 2019. This is a must do!

You cannot cycle any higher than this in North America.

There are not many rides you will do where you can say, "This is the highest . . ." but this is one of  them.  Mt Evans, Colorado -- the highest paved road (therefore the highest paved climb by bike) in North America!  For all that strive to climb the hardest, the longest, the steepest, the highest, this is a must-do!  

Last five miles to the top.

Mile markers correlate to the start of Mt Evans Road at mile 13 of the full climb.

You  will encounter unique wildlife as you climb this mountain, including Rocky Mountain bighorn sheep,  mountain goats, deer, and marmots.  The marmots in particular seem very curious and you likely will encounter them staring at you along the side of the road towards the very top of the climb.

Our climb begins in Idaho Springs, Colorado with a four mile warm up at 3.1%.  Colorado is a mecca for climbing, particularly high altitude climbing, and routes across the Continental Divide.  We travel along Colorado State Highway 103 for the first 12.9 miles before making our only traffic turn on the route onto Mt. Evans Highway.  


Ride 12.9 miles, gaining 3,090’ to elevation 10,632, at 4.5% average grade.

. . . and 1.2 miles -- just about to the most challenging part of the ride.

This is the highest high-altitude cycling you'll ever get on a road bike in North America, so be prepared.  3% less oxygen for every 1,000' of climbing (42% less oxygen at 14,000' than at sea level).  It is highly recommended that you climb a few of the "lower" peaks in the area before tackling Mt. Evans. I was a bit light headed and wobbly towards the top my first of three trips up Mt. Evans. I had climbed several 8,000' peaks in California the week before the trip, but that didn't sufficiently prepare me for another mile of climbing after 8,000'!

Be aware that the top 5.3 miles of  the climb are limited to foot and cycling traffic after Labor Day (as of 2014) and closed to cyclists/hikers whenever weather dictates.  You will have no SAG support after Labor Day from mile  22.1 (Summit Lake Park) to 27.4 (summit).

3 months into my chemotherapy treatment for lymphoma I decided that if it looked like I would be o.k. at the end of my treatment, I would try an epic cycling climbing challenge - riding North America’s and the US’s only 2 paved 14ers in a day.  On September 9, 2021, I did it 👍👍 - 

This is a great challenge and please do ping me if you decide to or have done it - I appreciate hearing the story of others who have done, or intend to do, fun and epic cycling challenges - 


When to cycle Mount Evans:  “The Mount Evans Road and Scenic Byway (Colorado Highway 5) is typically open the Friday of Memorial Day weekend through the first weekend in October, depending on weather conditions. The road and access to the top of Mount Evans is closed at Summit Lake the day after Labor Day. For the latest information about the road visit [this website]”  (Forest Service - Mount Evans).

How to Cycle Mount Evans: Train as much as you have ever trained for any climb.  This is an extremely challenging road bike climb due to the altitude we ride to (there is 42% less oxygen at the summit than at sea level). We suggest at least a compact chain ring and 28 to 30t cassette.  The climb begins 2/10's of a mile southwest of the intersection of Highway 40 and Chicago Creek Road in Idaho Springs, Colorado, 55 miles west of Denver International Airport (39.73919, -105.52242 latitude/longitude).

Before heading out on your Mt. Evans cycling adventure, be sure to rely on our list of Things to Bring on a Cycling Trip, and use our interactive checklist to ensure you don't forget anything.

Photo:  Bicycle Race 

Each July cyclists race from Idaho Springs (7,560’) to the end of the pavement above 14,000’ in the Bob Cook Memorial Bicycle Race.  This ride is named after Bob Cook, who died of melanoma at age 23 after having won the race an unbelievable six times in his young life. The race has been held every year (except three) since its inaugural in 1962.  Professional (or soon to be professional) cyclists have won the race over the years, such as: Alexi Grewal 1981, 1984, 1990; Ned Overend 1985-1986; Michael Engleman 1991-1995; Jonathan Vaughters 1997, 1999; Scott Moninger 1998, 2000-2002; Tom Danielson 4004, 2007, 2009; Peter Stetina 2010; LeRoy Popowski 2011-2013; Christopher Carr 2013; Lachlan Morton 2015; Chris Butler 2016; Chad Haga 2017; and Gregory Daniel 2018.

Roadway and Traffic:  Miles 0-13 are along Highway 103 (Chicago Creek and Squaw Creek Roads). The highway surface is a smooth two lane road with no bike lane,  but minimal traffic, particularly along the last several miles before the Mt Evans Road turn off.  Traffic is mild for the entire climb on Mt. Evans Road (14 miles) and the roadway surface good, although a little rough for the five mile descent from the top to Summit Lake.  Additionally, as of summer 2020, there are expansion ruts (linear gaps) in the roadway along the top section of the climb which make descending uncomfortable and potentially hazardous.

Great summaries of Mt  Evans are found at Steep Climbs and Mt. Evans.
