Due to the impacts and safety around the COVID 19 response, we have unfortunately had to cancel the 2020 Iron Horse Bicycle Classic. We look forward to a great 2021 event on Memorial Day Weekend May 28-30th, 2021. Look for our online registration to open December 5th, 2020.

Registration fee is $104 through December 31, 2019, and increases to $114 on January 1, 2020. The field is limited to 1900 riders.
For participants who register before March 31, 2020, bib numbers will be mailed to you mid April, with the exception of zip codes 81301/81302/81303/81122/81137/81326.

$10 of your entry fee is donated to numerous community organizations, including the Mercy Health Foundation.

Important Information:

All riders must attain Coal Bank Pass by 12:40 p.m. and Molas Pass by 1:20 p.m. Riders not past those points will be transported by bus to Silverton, and their bikes will be trucked. The highway will open to vehicles at 1:30 p.m. and all riders must be off the road by then. Bicyclists are not permitted to ride back to Durango, so you must take private transportation or register for the $40 event-provided return transportation that includes your bicycle.
Due to the road closure, no team or support vehicles are allowed on course. Riders must be self-sufficient. There are four official support stations throughout the course. Yellow-line rule is in effect for the entire course, including the closed-road portion. Please be cautious and aware of emergency vehicles on course.
All registrations are final. If the event is cancelled due to inclement weather, there will be no reimbursement, rollover, or postponement.

Return Transportation:

Riders who need return transportation from Silverton can register for the $40 event-provided return transportation that includes your bicycle. Bicycle pickup is 3-7 p.m. at Durango Transit Center 250 W. 8th Street. Participants are not permitted to ride their bikes back from Silverton. When you register for a Saturday event, return transportation will be an option you can add at that time.
