Runners will head north out of the ZooMontana Parking Lot and make their way up and around the conservation area and back.
Bikers will head south out of the ZooMontana Parking lot. They will cross over I-90 then wind their way along the backroads out to Laurel via River Rd. And yes, you will be riding over and along the Yellowstone River.
MAPS WILL BE POSTED SOON*
There will be 2 Aid Stations along the Bike Route. All other water and aid stations will be at the Transition area.
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!

These values represent the 3-year monthly averages for June in Billings.
Billings is the largest city in Montana in Yellowstone County, with an estimated 110,000 people (2019). As a destination, Billings does a significant amount of convention business and is also the host to various regional events such as music festivals, athletic contests, rodeos, and outdoor activities. Billings hosts the largest hospitals in a 500-mile radius, as such the medical profession is a major source of employment in the area. Billings also is a frequent overnight or meal stop for westbound visitors to Yellowstone National Park, as it is the last major city for visitors going to the park via the Beartooth Highway.
