Performance enhancing drugs in UltraRunning? Well not exactly...but Karl King has come close with S!Caps. Karl's contribution to the trail is legendary: Sodium 341 mg + Potassium 21 mg add heat + elevation, let simmer for a couple hours and you are ready to serve up a great day on the trail. In this podcast Karl shares with us how he developed S!Caps and ways we can use them to improve our trail experience. Thanks Karl King!
