The Leadville Trail Marathon is 26.4 miles of out-and-back dirt roads and single track that takes you through the historic mining district on the east side of Leadville. The Heavy Half consists of 15.46 miles along the same path as the marathon minus the Ball Mountain section. The course is primarily on old mining roads and trails, topping out at 13,185 feet at Mosquito Pass. This is the HIGHEST continuous pass in the country and the highest trail Marathon in the USA! There is a chance you’ll see snow on the course. The courses will be well marked with fluorescent pink-and-black striped ribbon and flour arrows on the ground.

Weather – remember that you will be racing in a high-alpine environment with the possibility of extreme weather. If there is thunder or lightning, seek lower elevation quickly.

We recognize crews as a critical component to all of our events. Our courses cover open roads and trails and careful consideration must go into how and where crews can access their athletes. A conscious plan around this is a foundation of our partnership with the community, USFS, BLM, City of Leadville and Lake County officials to ensure we are providing a safe event experience to everyone involved.

To support local community impacts and maintain safety on public roads, the only areas where crew and and spectators are allowed on course are:

1. Start/Finish Area
2. Resurrection Aid Station

Resurrection Aid Station can be accessed in TWO ways:

1. Driving from the community lots to Resurrection Aid via 7th St. Please use the map linked below and DO NOT drive on the course.
2. Crew shuttles will be available from the startline to/from Resurrection Aid Station. Please help us reduce course congestion and plan to use the crew shuttle.

Parking and overall congestion in Leadville will be a crucial topic for everyone this season and for our presence in Leadville moving forward. We know that with your help we can be great stewards of this community for years to come!

All athletes and crews will be required to park at the Community Fields and High School Parking lot and take a shuttle (or run, walk, bike) to the start line. There will be NO parking at the startline. The map below outlines parking locations and shuttle pickup spots. The shuttle locations are under 1 mile from the race start and will run efficiently and quickly to get you to where you need to be! 

SHUTTLES WILL BEGIN AT 5:00 AM AND RUN ALL DAY.

Train with what you’ll use on Race Day! You can find the following products at aid stations for all Leadville Race Series Events:

Skratch Labs – Hydration Mix, Energy Bars & Chews

Neversecond – Energy Gels and High-Carbohydrate Sports Drink

Learn how to do Leadville Twin Lakes right

Care for Colorado Leave No Trace Principles

Plan Ahead + Pack Smart

• Know the Course – Study the route, aid stations, portapotty locations, and terrain before race day.
• Pack Light + Right – Bring only what you need (hydration packs, snacks, gear); choose reusable or biodegradable gear.
• No Littering – Be prepared to deposit waste at Zero Waste Stations throughout the course. Intentional littering on the course will be grounds for disqualification. 

Camp with Care

• Know Your Options – From dispersed sites to RV parks, plan and book early. Check if CMC offers event-specific camping.
• Dispersed = Primitive – First-come, first-served camping on public lands. No services provided. Camp 100+ feet from water and follow fire rules.
• Self-Reliance is Key – No bathrooms, no trash service. Pack it in, pack it out. Stop by the Visitor Center for pet waste bags.

 Bathroom Rules

• Use Portapotties – Provided along the course and at aid stations. No exceptions.  LRS is offering expanded portapotty options in 2025 and beyond.
• Backcountry Emergencies – Dig a 6″ hole 200 feet from water. Penalties apply for non-compliance. Carry a WAG bag for TP and hygiene items.

Respect the Land

• Historic Sites Matter – Crews are no longer allowed at the Twin Lakes Forest Service site due to past damage.
• Leave What You Find – Don’t move or take natural or cultural objects.

Fire Safety

• Check Restrictions – Before lighting any campfire, confirm local fire bans.
• Keep it Small + Cold – Never leave fires unattended. Fully extinguish with water until cold to the touch.
• Buy Local Firewood – Available at ACE or Big R in Leadville. Don’t import pests.

Wildlife Awareness

• Bear Smart – Keep food, trash, and scented items in bear-proof containers or locked vehicles.Twin Lakes has issues with trash attracting bears. 

Respect the Locals

• Be Courteous – Don’t block driveways, urinate in private yards, or disrespect residents. Your behavior reflects on the entire race.

Check out our Official Rules page to familiarize yourself with all policies that ensure a fair and safe experience for all.
