Iron Horse Bicycle Classic

It began with a candy bar and a dare between brothers. In 1971, Tom Mayer challenged his brother Jim, an engineer on the Durango and Silverton Narrow Gauge Railroad, to beat the train to Silverton on a bicycle. Tom won. The following year, 36 riders accepted the same challenge; five of them beat the locomotive. The Iron Horse Bicycle Classic has operated from that founding premise ever since, growing from a local eccentricity into Colorado’s largest, oldest, and most consequential cycling event over more than five decades. The 2026 edition runs May 22–24 in Durango, Colorado, with the Coca-Cola Road Race on Saturday, May 23, as the competition’s irreducible core: 47 miles from Durango to Silverton, two mountain passes above 10,000 feet, 6,700 feet of climbing, and the Durango and Silverton Narrow Gauge Railroad chugging the same route on parallel track.

The weekend’s structure accommodates a genuinely diverse field. The Coca-Cola Road Race is the competitive event, with the McDonald’s Citizens Tour running simultaneously on the same route for participants who want the experience without the racing context. The Purgatory Quarter Horse covers a 25-mile route to Purgatory Resort, appropriate for families and less-experienced cyclists who want a mountain riding experience scaled to their capabilities. Sunday brings the Alpine Bank La Strada La Plata Gravel Ride and the Subaru Mountain Bike Race, with the Sprite Kids Race and Alpine Kids Village providing a dedicated youth circuit and activity zone at Buckley Park. Friday, May 22, opens the weekend with local packet pickup and the Faceplant Ale Kickoff Parade, which departs Ska Brewing at 5 p.m. in costume-encouraged fashion and winds through Durango’s downtown to Buckley Park. Over 3,500 participants typically attend across all events.

The Route and What It Demands

The 47-mile road course from 33rd Street and 2nd Avenue in Durango to the Silverton finish line covers Coal Bank Pass at 10,640 feet and Molas Pass at 10,899 feet, both on US-550, the Million Dollar Highway. The descent from Molas into Silverton is one of the most technically engaging road cycling descents in the Southwest, with tight switchbacks, sheer drop-offs on the outside edge, and a surface quality that rewards smooth lines over aggressive braking. Citizens Tour riders complete the same route and arrive to the same Silverton finish line, where the narrow-gauge train has either already arrived or is pulling in, depending on the day’s conditions.

If You’re Going with Kids
The Sprite Kids Race at the Fort Lewis Clock Tower on Sunday morning and the Alpine Kids Village at Buckley Park are the dedicated family programming, designed for young riders across age brackets from first-timers to competitive juniors. The Faceplant Ale Kickoff Parade on Friday evening runs along Durango’s Main Avenue and requires no advance registration, making it the most accessible entry point for families who want to experience the event’s energy without committing to a competitive format.

Durango and the Animas River

Durango’s Main Avenue district, built around the arrival of the Denver and Rio Grande Railroad in 1881, retains an urban vitality unusual for a Colorado mountain town of its size, with independent restaurants, outfitters, and an arts scene distributed across a walkable downtown. The Animas River Trail, a paved path running from the Depot district through the college neighborhood and north along the river, provides a flat morning ride or walk that bookends the race weekend’s intensity with something genuinely restorative. Navajo Reservoir, 35 miles south near Arboles, is one of Colorado’s most productive kokanee salmon and walleye fisheries and warrants a side trip for anglers adding a fishing day to a race weekend in the Four Corners region.

Where to Stay

Durango’s Main Avenue hotel and boutique lodging inventory is within walking distance of the race start. The Strater Hotel at 699 Main Avenue, open since 1887, is the most historically embedded lodging option in town.
