Permitting & land use

Who owns the ground

Around Leadville the course will touch, in rough order of how much of it you'll use:

• U.S. Forest Service — most of the passes and mining roads sit in the Pike-San Isabel National Forests & Cimarron and Comanche National Grasslands (PSICC). The relevant office is the Leadville Ranger District, 810 Front Street, Leadville CO 80461, (719) 486-0749.
• Bureau of Land Management — some lower stretches and connectors cross BLM land, handled through the local BLM field office via a Special Recreation Permit.
• County roads — Lake County (Leadville), and depending on route, Park, Chaffee or Gunnison counties. County road-use and any road-closure or traffic-control needs go through the county.
• CDOT state highways — e.g., Independence Pass is State Highway 82. Racing on an open state highway generally isn't permitted; either avoid it, use it neutralized/transfer only, or arrange a CDOT special-event review with certified traffic control.
• Private land — the Sugarloaf Mountain Ranch (1,000 acres) is the ace: on private ground you need the owner's agreement and your own insurance, not a public land-management permit. It's the one part of the course with no agency queue.

The USFS special-use event permit (your critical path)

The Forest Service issues special-use permits for organized, temporary recreation events — the category explicitly includes bike races. A permit is required for groups of 75 or more and for all commercial activity (a paid-entry event is commercial), so a stage race clearly needs one.

How it goes

1. Pre-application conversation with the Leadville Ranger District. Bring a route map, dates, expected field size, and your safety/sanitation plan. They'll tell you feasibility and what review level applies.
2. Application (the FS event proposal / SF-299 for the use) with route, schedule, participant numbers, and operating plan.
3. Environmental review under NEPA — often a categorical exclusion for a low-impact event on existing roads, but that's the district's call and it takes time.
4. Operating & mitigation plan — Leave No Trace, sanitation (toilets), trash, marking that's removed after, resource protection, and coordination with other permit holders and the public who also use these roads.
5. Fees — expect a land-use fee (a percent of adjusted gross, or a per-participant basis) plus cost-recovery for the agency's processing/monitoring time. Get the number in writing early; it feeds the budget.
6. Insurance — the FS will require you to name the United States as additionally insured at a set liability limit (see Sanctioning & insurance).

Everything else, in parallel

• BLM SRP — if any stage crosses BLM land, file a Special Recreation Permit with the field office; similar cost-recovery + fee model, own timeline.
• County — road-use permits, and for any closure or flagging on county roads, coordinate with the county road department and sheriff. Some counties want a special-event application of their own.
• City of Leadville / Lake County — start, finish, expo and any street use in town; venue use at county facilities.
• Private ranch — a written use agreement with the owner, your certificate of insurance naming them, and a plan for gates, cattle and stewardship.

Sequencing — do it in this order

1. Call the Leadville Ranger District first and get the real lead time; that date drives everything.
2. Lock a candidate route good enough to permit (see Course design), knowing it may shift to satisfy land managers.
3. File USFS + BLM + county applications together so their reviews run concurrently, not back to back.
4. Secure the ranch agreement and the in-town venues.
5. Bind insurance and sanctioning so you can name the required insureds on every permit.
