Thursday, May 14, 2020–postponements and cancellations to date
The Leadville 100 was scheduled for August 22 and 23, but it has been cancelled. Runners already registered for the event have several options regarding their entry fees. Runners can donate to a lunch program in Colorado’s Lake County School District or to the Leadville Trail 100 Legacy Foundation, which funds scholarships for Lake County high school graduates (runners who choose this option will be given “non-complimentary entry” into the 2021, 2022 or 2023 races). There is also a deferral option, and runners can wait to race until 2021, 2022 or 2023. Finally, there’s the option for refunds.
goal races this year:
Western States: canceled
Leadville 100: canceled
