Despite our best efforts to clear Mosquito Pass, Mother Nature has prevailed with heavy snow and freezing temperatures and the Life Time Leadville Trail Marathon & Heavy Half presented by La Sportiva will unfortunately not be able to reach the summit of Mosquito Pass on Saturday.  

We have altered both courses to turn around slightly below the summit and additional mileage has been added elsewhere to maintain course distances of 26.2 and 15.7 miles respectively. Updated course maps can be found below:

Read a Note from Race Director Tamira Jenlink below:

“Hello Leadville Race Family! We look forward to seeing you on the start line of the 2023 Life Time Leadville Trail Marathon presented by La Sportiva on Saturday!

This year has most certainly kept true to the nature of Leadville with snow still falling above 11,000′ as I write this. Our crews have used every ounce of GRIT, GUTS and DETERMINATION possible to remove the last 1.5 miles of snow on Mosquito Pass. While this is still a bit short of the top, we will absolutely not disappoint! We have made minor modifications to the course to ensure every mile will continue to deliver those lung busting climbs, and spectacular views you have been training for, while ensuring your safety and overall experience. 

Don’t forget your mittens and maybe a jacket as you may very likely have the quintessential experience of !  running in the snow! See you on Saturday!”
