Athlete Driven Endurance Coaching

Coach Sarah Portella is a triathlon, run, and cycle coach with Bolton Endurance Sports Training.

Training programs are uniquely designed for each athlete and their goals. By learning about each athlete and their current lifestyle, I can create a training program that balances life and training.

The key to an athlete’s success is their ability to complete and be consistent in the training plan designed for them.
