Leadville Marathon 2022-86

June 29, 2024

Simply put, the nation’s toughest — and highest — marathon. The Life Time Leadville Trail Marathon and Heavy Half presented by La Sportiva takes trail runners through the historic mining district’s challenging trails to the highest point of any Leadville Race Series event: Mosquito Pass (13,185 feet). As you take on the baddest trails and thinnest air in all of endurance racing, you’ll need all the Grit, Guts and Determination you can muster.

NEW – The Life Time Leadville Trail Marathon & Heavy Half will take place on June 29th, 2024 (two weeks later than previous years).

The 2024 Schedule has not been finalized. Please see the 2023 event schedule below for reference.

Race Start!

Below are some quick updates and reminders for all 2023 Leadville Trail Marathon & Heavy Half athletes.

1.) This race typically fills up and there is no on-site registration. There will be no changes permitted to your original race distance registration.

2.) We will be in alignment with CDC guidelines and the Lake County Health Department with regard to COVID-19. Check back for updates.

3.) 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.

4.) We will now have a rolling start instead of assigned waves/corrals for both distances. There will be signs at the start with each pace & projected finish time. You will seed yourself. See below for a list of suggested seed times.

5.) The race is chip timed, meaning your overall time will be based on when your race bib crosses the start and finish line.

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 and spectators 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 have a new parking plan in place for 2022 and we know that with your help we can be great stewards of this community. 

All athletes and spectators 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 athlete or spectator 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!

Our races aim to be Zero Waste. Look for recycling and compost bins at every aid station and start/finish. Please discard any waste in an appropriate container. Intentional littering on the course will be grounds for disqualification. The course—on trails both public and private—travels past many historic sites and through areas of exceptional beauty. Help us keep them pristine.

  • This is a zero waste event. 
  • Our local zero waste non-profit, Cloud City Conservation Center, is hosting our recycling program.
  • There will be recycling/compost containers at all full aid stations and at the start/finish line.
  • Please place any waste in the proper bin. 

Reminder – Intentional littering on the course will be grounds for disqualification.

Volunteer registration for the 2023 season will open on March 1st, 2023.
