JUNE 19th, 2021



Run through the historic mining district’s challenging old mining roads and trails, and hit a high of 13,185 feet at Mosquito Pass during the Leadville Trail Marathon or Heavy Half Marathon. The views will leave you breathless, if you’re not already. The marathon will mark its 19th year in 2020, while the Heavy Half will mark its 15th.


Each Leadville Qualifying Series race provides 25-100 qualifying slots to the Leadville Trail 100 Run presented by La Sportiva, based on the total number of registered racers at each qualifier event. Half of the qualifying spots will be allocated based on the top age-group performances and half will be drawn among runners who have finished the qualifier race within the allocated cut-off time.

Qualifying slots will be distributed at the Awards Ceremony. Qualifying slot winners MUST BE PRESENT, as the roll-down qualifiers rule will be in effect at each event. All qualifier slots will be awarded and redeemed on race day. You must pay your entry to the LT100 Run within the three days after the event. You will have the option to register for the current year or the following year’s LT100 Run and must decide when accepting your qualification slot. All entries into the LT100 Run are non-transferrable.

Our races are Zero Waste events. Look for recycle 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.

From the very beginning, volunteers have made the Leadville Trail Marathon & Heavy Half possible. We truly appreciate all that our great volunteers do to make our races run smoothly and to make the racers’ experience unforgettable. If you are going to be in town for the Trail Marathon & Heavy Half, we would love for you to join the family and pitch in. Thanks in advance for your help — we couldn’t do it without you!
