Event: Yellowstone Half Marathon - Charity Bibs $1000 fundraising commitment
As part of our ongoing efforts to raise money for the National Park Foundation, we’re offering the option to register with Charity Bibs for the Yellowstone Half Marathon! Please note that registering for a charity bib is a serious commitment.

To get one of the charity bibs you will need to raise $1000 through our registration system. 100% of the money raised will go to our partner the National Park Foundation! Once you sign up for the charity bib, you’re committed to raising all of the $1000, so please do not take this lightly.

HOW IT WORKS: First, you’ll register for a charity bib– just select the “charity bib” option when you register for the race. Once you have completed registration you are on the hook to raise $1000. You have until 2 weeks before the event to get donations from friends and family. You’ll be provided a link to send anyone where they can donate and contribute to the $1000. If by that date, you are short of the $1000, you will be charged the remainder. So, for example, if you raise $900 by the May 20, you will be charged $100. If you raise $1000 or more, you will not be charged anything.

Your race registration is also included in your charity bib registration, so you’ll be asked things like preferred shirt size, hydration method, etc.

We’re excited about this opportunity to raise additional money for the National Park Foundation and to do some more good for the parks!
