SUP ATX and RunTex are two companies that are meant to be together. Paul Carrozza founded RunTex over twenty years ago, establishing Austin as the fitness-crazed city it has become. Nick Matzorkis founded SUP ATX four years ago as the largest stand up paddle board maker on Earth and in the process has established Austin as the Paddle Board Capital of the World. Many say that SUP ATX has done to Austin lakes what RunTex has done to it's streets and running trails. It make so much sense that these two companies would come together to continue to lead Austin in the 21st century as a health and fitness role model for other cities to follow. The official SUP ATX showroom is located in RunTex on Lake Austin Blvd, only steps from Lady Bird Lake (formerly Town Lake).

The SUP ATX showroom in RunTex offers paddle board sales, clothing and accessories. Paddle board rentals are available during all daylight hours, 7 days a week, at the Texas Rowing Center just a couple hundred yards away directly on Lady Bird lake. Free paddle board demos are also held weekly from this location. Store Hours and Directions.
