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.
There will be three well-supplied aid stations for the Heavy Half and seven aid stations for the Trail Marathon.

There is a lot of mixed information when it comes to eating or drinking in the last hour before competition. Taking in some carbohydrate may help, because it provides extra fuel that may be needed, especially during longer events. However, it can also result in so called rebound hypoglycemia or reactive hypoglycemia with symptoms of weakness, dizziness and nausea. So, it can have positive as well as negative effects? What should we do? This blog will give you the ins and outs.

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:
- Start/Finish Area
- Resurrection Aid Station
Resurrection Aid Station can be accessed in TWO ways:
- Driving from the community lots to Resurrection Aid via 7th St. Please use the map linked below and DO NOT drive on the course.
- 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.
Shuttle schedule:

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!
