Walk and Community Days are an opportunity for communities across the nation to gather and raise funds for individuals with compromised immune systems. These impactful, enlightening, family-friendly events are inclusive and welcome to all supporters.
Donate your time to our Walks to support immunocompromised individuals. Volunteers can help promote the event, or be there on the ground, helping with logistics, directions, or registration.
Participants who raise $100 or more will earn a special commemorative Walk and Community Days t-shirt recognizing their commitment to supporting the PI community. Additional fundraising incentives are available for those who go above and beyond, such as the special Order of the Zebra honor for individuals who raise $1,000 or more. These opportunities offer exciting rewards for participants who help make a significant impact through their fundraising efforts.
Connect with the national Walk community on Facebook. Through the public group, you can ask questions, meet others, invite friends and family to join, and more.
