Trainers Who Care


Sandra Sutherland 

Founder of TXTRI is committed to Endurance training and coaching. Racing is the fun part! We take your fitness goals seriously and make sure you are safe and balanced in all for each sport. Training all components of the sport: equipment, technique, and building on personal experience to apply the latest and best technology to keep you safe and enjoying the great outdoors!  We understand that having a healthy weight is important and can be challenging, and our goal is to help educate and teach the basics of nutrition with sports to reach your goals. Custom programs will all include nutrition as part of the process and success of the sport. Energy is part of the training! Recovery too! 

Our sponsors play a role in our support and the team effort to healthiness is all part of TXTRI. Welcome!
