The Road ID mission is two-fold: One, to educate outdoor enthusiasts about the importance of wearing ID. Two, to provide these athletes with innovative identification products that they will want to include as part of their gear.

For 2024, we are thrilled to announce that Road ID will be offering an exclusive Badwater 135 edition band and ID for all participants this year!

Created in collaboration with race director Chris Kostman, this special edition features the topography of the course as it winds through the breathtaking landscape from Badwater Basin across Death Valley to Mount Whitney.

We hope that this personalized band and ID will provide peace of mind and motivation as you embark on your 135-mile journey, and also serve as a meaningful keepsake.

Founded in 1990, De Soto Sport has established itself as one of the most visible brands of apparel at any triathlon around the world. Founded by former pro triathlete, Emilio De Soto II, the San Diego-based company leverages experience dating back to 1980 in international triathlon and endurance sports competition into every product it creates.

De Soto makes technical garments for men and women designed with comfort and style, most of which can be used for swimming, biking, and running, eliminating the need to change.

With over 50 years of experience in camping, hiking, back-country mountain biking, snowboarding, surfing, trail running, and yoga, the De Soto Collection also offers a complete line of workout apparel, accessories, cold climate base layers, and gear – all of which transcend well into many other sports and exercise.

The company has been managed by Emilio and his wife, Tracy, since 2009.  Both left endurance sports competition to dedicate their time to raising their three boys who are on swim team and have started competing in multi-sport events.

De Soto Sport is the Official Apparel Partner of Badwater® and produces a line of one-of-a-kind, hi-tech and Badwater-branded garments for running, bicycling, cold weather, and the Badwater Way of Life.

A collaboration between Emilio De Soto and Chris Kostman, the designs celebrates the spirit of one of the world’s toughest race series.
