Mt. Washington is the U.S’s equivalent of the legendary Italian climb of the Passo di Mortirolo, one of toughest and most feared climbs in the world, regularly used in the Giro d’Italia that brings a lump in throat to the most seasoned professional riders.

5,161 feet, 24.1 miles - Spartanburg, South Carolina, May 14, 2018

Mount Mitchell has one of the greatest elevation gains of any climb in the United States, and the climbing styles are very diverse.

After several tunnels and a descent, the climb resumes on Mount Mitchell State Park Road, which is a bit steeper than earlier climbing.

6. Mount Lemmon Hill Climb

6,600 feet, 21 miles - Tucson, Arizona, May 4, 2018

Mount Lemmon is one of the nicest climbs in the southwest of the U.S. It's a long, steady climb with near perfect tarmac - a real hill climber’s paradise. Mt. Lemmon is a rare jewel in the Arizona desert. Jutting up 9,157 feet (2,791 meters) above sea level in the Santa Catalina Mountains north of Tucson, Arizona, this magnificent mountain peak stands amidst the pale backdrop of the sparse desert sand and cactus. Not far from Tucson - a haven for Professional teams in the warm winter climate.

Mount Lemmon received its English name in honor of botanist Sarah Plummer Lemmon, who trekked to the top of the mountain with Native American guides by mule and foot in 1881. Sara Lemmon is also known for getting the Golden Poppy adopted as the California State Flower in 1903.

Hardly anywhere else in the US can you climb so high for so many miles in succession. Mount Lemmon is in the top 25% of toughest hill climbs in America - with a rating of HC "hors category" on the scale used to rank climbs in European stage races, like the Tour de France.

Mount Lemmon is right up there with the famous passes in the Alpes, Dolomites and Pyrenees. 

In comparison, the Colle dell'Agnello (Italian) or Col d'Agnel (French), used in last years Giro d'Italia, is situated in Provence-Alpes-Cote d'Azur region on the French / Italian border and belongs to the Alpes range of mountains. Starting from french town of Guillestre, the Col d'Agnel ascent is 26 miles. Over this distance, you climb 1,736m. The average percentage is 4.5 % and this climb has been used twice in the Tour De France and Giro d'Italia. Very similar to Mount Lemmon in distance, difficulty and height - although the Italian side is much harder.

Mount Lemmon grade averages 4.5% for 6,600 feet (2012m) of elevation gain over 27.5 miles from base to the top. The temperature on the way up to Mt Lemmon is 20 to 30 degrees colder than the Tucson area. Weather can also change quickly. Check the weather day before the ride to know the conditions and bring appropriate clothing to keep yourself warm, like armwarmers and a gillet.

The almost continuous 26-mile descent down is exciting without ever being terrifying, so the total round trip of 56 miles.

The Mount Lemmon Hill Climb is organized by the Greater Arizona Bicycling Association. An early start is required!

9. Whiteface Mountain Uphill Bike Race

3,539 feet, 8 miles - Wilmington, New York, June 1, 2018

Located in the Adirondacks of up-state New York, this climb is almost identical in length and grade to l’Alpe d’Huez, considered one of the most difficult climbs of the Tour de France.

Whiteface has been open to bikes during regular hours for many years now. They charge $8 for bicycles so you can train on the climb too.

Plan an hour and a half to tackle it (though the record stands at 43 minutes). The grade is sturdy right from the start, so a warm up is probably a good idea. After three miles and a toll booth, the grade averages ten percent for three miles. Closer to the summit, the slope finally eases, the trees clear, and views begin to appear. A few large and graceful turns lead you higher on the mountain over moderate grade.

The climb ends where the road dead-ends at the upper end of the parking lot, from where you can hike or take an elevator to the very top of the mountain.  The visitor’s center is in Whiteface Castle, at the peak’s crest, where you can see all the way to Vermont and Canada on clear days.

The race is 11 miles, though it starts at the ski mountain with 3 miles of flat-downhill to the base of the climb. It's an average of 8% with 3,539 feet of climbing.

Fruit, snacks and beverages are served in the Whiteface Mountain Hill Climb at the Finish Line and Post Race Meal is served after the race which is included in the entry fee.
