Why We Race
STAMPEDE is more than a competition — it’s a chance to support wildlife, conservation, and community.
A portion of all proceeds goes directly to ZooMontana's on-site Veterinary Clinic, helping provide crucial medical care for the animals that call the zoo home.
Wild & Well: A New Era of Animal Care begins with building an Animal Health Center. This building will not only allow us to provide comprehensive veterinary care on-site, but will also create opportunity for educational partnerships for our community. We are thrilled to break ground, but we can't do it without your help. This campaign has raised $1.9 million of our $3.9 million goal. Every gift, no matter the size, makes a difference for our animals, community, and the future of ZooMontana. Consider donating to our capital campaign to help us build this facility!
