TMC Earth Day 5K at Biosphere 2

Sat April 20, 2024 Oracle, AZ 85623 US Directions

Discounted visitor pricing + other visitor details

Discounted Visitor Pricing: All runners receive free entry to the Biosphere 2, while all all Earth Run spectators 13 years and older receive the reduced general admission fee of only $10 per person. Children 12 and under are free between the hours of 6am and 10am. Your admission not only gets you access to the grounds but is also good for the Biosphere 2 Experience. 


The Biosphere 2 Experience app helps guides you around and through Biosphere 2 and includes never before seen photos and videos that visualize the science and 30-year history. Through science stories and interviews you'll have the opportunity to learn more about our amazing, world-class research as you traverse a safe (socially distanced) one-way path around the exterior and through the human habitat and wilderness areas of Biosphere 2. Your admission fee helps to support Biosphere 2’s education and research initiatives.


Accessibility: While the race course is accessible to all, please be mindful of hills and varied terrain. Much of the Biosphere 2 campus is wheelchair accessible, though certain areas of the property are not accessible due the steep terrain and the presence of stairs. The majority of the biomes, including the desert, savanna, ocean and rain forest, are all accessible by wheelchair or scooter.


Pets and Service Animals: While pets are not allowed inside Biosphere 2 or on the grounds, service animals that are trained to do a specific task are welcome. Please do not leave pets unattended in vehicles.
