"I've been training with Maria for about 3 years. I wouldn't have wanted to complete my training seasons without her! I love having the support and encouragement from a coach that not only talks the talk but walks the walk! No Limits' experience in the endurance racing community allows them to provide the most comprehensive and knowledgeable training "package" out there, no matter what your distance, pace, ability or experience level." ~Steph R., New Jersey

"Maria is a great motivator both through her own athletic achievements and overall bad-assery. Communication is natural and there is really nothing that I cannot tell her. Her genuine concern is a great comfort to me and there is no limit to the amount of communication we have. Her analysis, and more importantly her explanation, of the data is where I appreciate Maria the most. Maria does an excellent job of keeping my goals in perspective. I would not be where I am currently at and headed to, athletically, without the guidance of my coach, my friend, Maria." ~Kelly C., New Jersey
