Join us for our most unique race ever! Starting in the Natural Bridge Caverns, which is part of the Comal Caverns network, this race kicks off with breathtaking views of the world below our feet as the start line is in the depths of the Natural Bridge Caverns. Once you emerge to the sunshine of a beautiful day, you’ll wind your way through beautiful trails over flowing hills and through wooded sections. You can choose from 4 to 16 miles distance or go big with the Last Person standing format.

This race is made possible by the great work of Great Springs Project. Don’t know what that is yet? Check out this link or just come to the race and learn how the Edwards Aquifer under these trails is critical to sustainable clean water for our growing cities. We are incredibly proud to support their grandiose efforts, alongside the city of San Antonio via this trail race!
While every racer will get some cool swag, September 1 is the deadline to get a shirt.
