Each year, athletes show off their prowess in a series of mettle-testing, muscle-busting bike races, mud runs and other extreme Colorado competitions. If you want to suit up and jump in or watch from the sidelines, here are a few of the gnarliest extreme races across the state.
Tough Mudder: Sept. 10–11, 2016
Designed by a decidedly dark-minded team of British Special Forces, Tough Mudder events span the country bringing hard-core obstacle courses to athletes willing to test the limits of their stamina, strength and sanity. Participants risk hypothermia, burns and electric shock in challenges with names like the Fire Walker, in which athletes run through a corridor of four-foot-high flames, and the Electric Eel, wherein contestants belly-crawl along sheets of ice while live wires dangle mere centimeters from their heads. Copper Mountain’s Warrior Dash (Sept. 17, 2016) lays out similarly hectic travails.
Colfax Marathon: May 21, 2017
The popular Mile High urban tour winds through Denver’s eclectic neighborhoods, into the iconic Sports Authority Field at Mile High and along one of the country’s most colorful roads, Colfax Avenue. The Colfax Marathon attracts legions of people each year and incorporates one of the largest charity partner programs in the country.
GoPro Mountain Games: June TBA, 2017
Like the Olympics, this annual Vail celebration of extreme mountain sports has both a summer and winter component and incorporates several different sports in varying disciplines. While staple competitions, like trail running and road cycling, are included, you can also catch less-familiar sports like extreme kayaking, surf cross, mud running, bouldering and a standup paddle sprint. Capping it all off is the GNC Ultimate Mountain Challenge, which pits athletes against one another in a medley of sports that includes a 10k, a trail ride, a road bike time trial and a rough-and-tumble kayak sprint. There’s also a photography competition, a film festival, an adventure film school and, of course, live music.
Ride the Rockies: June TBA, 2017
Now in its 32nd year, this non-competitive bike ride leads 2,000 cyclists in a cross-state tour of the Rocky Mountains that highlights Colorado’s rugged scenery. While terms like “tour” and “non-competitive” may confer an aspect of leisure upon the event, this ride is anything but easy. The route changes each year, but it always includes several rigorous climbs over steep mountain passes, and riders can expect to pedal anywhere from 40 to 100 miles a day.
TripleBypass: July TBA, 2017
In one of Colorado’s biggest road rides, 5,000 cyclists annually traverse 120 miles and three mountain passes for a total elevation gain of 10,000 feet. On the first day of this two-day event, about half the riders depart from Evergreen, ascend Juniper, Loveland and Vail passes, and finally unclip their pedals in Avon. The next day, the other half makes the same trip in reverse. About 1,000 iron-muscled warriors earn their Icy Hot by riding both days, in a feat known as the Double Triple Bypass.
Hardrock 100 Endurance Run: July TBA, 2017
Instead of crossing a finish line, the hardy participants in this ultra marathon are required to kiss the “Hardrock,” a gaily painted chunk of mining debris, to complete their trek. People come from all over the world to compete in the 100.5-mile run, which spans 13 major passes and is designed to maximize altitude, steepness, remoteness and (apparently) hurtiness. The race begins and ends in Silverton and includes a nasty 33,992-foot climb.
Leadville Trail 100 Run: Aug. TBA, 2017
This grueling, 100-mile ultra marathon through extreme mountain terrain is an out-and-back affair, which means that runners must tackle the race’s high point, Hope Pass at 12,620 feet, twice. Despite this, and despite the fact that fewer than half of participants finish within the 30-hour time limit, the “Race Across the Sky” has become an insanely popular endeavor. Held in Leadville, the race is now in its 34th year. In the same series is the Leadville Trail 100 Mountain Bike Race, also in August, which has attracted the likes of Floyd Landis.
