You must complete the 50K race in less than eight hours and 30 minutes to qualify for the Leadville Trail 100 run. Our desire is to see everyone finish, and we will support you the best we can. However, if we do need to remove someone for missing the cutoff, the decision of the race official is final.

Racers who are registered for the 50K distance will NOT be allowed to change and compete in the 20mi distance once the race begins. This will be an automatic DQ. If you are registered for the 50K and wish to change to the 20mi, please see the registration crew at packet pickup to switch the day prior to the race. Please know we are unable to provide a refund for the difference in price.

Please note: Due to safety restrictions on the course wheelchair participation is not permitted.

All runners will receive race bibs at packet pickup, and they must be worn and visible at all times on race day. Race bibs attach to your clothing and must not be cut or folded.

50K runners: keep the pull tab from your race plate for the LT100 Run lottery. This is your ticket to enter the drawing, which takes place after the 50K Awards Ceremony at 3:30 p.m. (see the Schedule for more information).


There will be trash bins and recycling containers at all aid stations and at the start/finish line. Please discard any trash in the appropriate container or within 100 yards of an aid station. We will be recycling all plastic and aluminum during each of our events. Intentional littering on the course will be grounds for disqualification. The course travels through areas of exceptional beauty. Help us keep them pristine!
