Hi, I’m Coach Cristina.

Hi There! In case we haven’t met, I’m Cristina. A coach, sports nutritionist, endurance athlete, wife  and mom to two little boys (and a fur baby).

I’m the founder of Fueled Coaching and Nutrition. I believe that life is too short to not do what you love. Helping athletes achieve success is one of my passions. Whether that’s through endurance coaching, sports nutrition, or a combination of the two, I’m excited to help you achieve your goals.

Family is extremely important to me, and getting to be a mom and coach means the world to me.  In my spare time you’ll find me racing triathlons, running races (trails are my favorite), open water swimming, cycling, stand up paddle boarding and participating in any adventure race that comes my way. I’m always up for a challenge!

If you’d like help reaching your goals, let’s connect.

Just the science, not the hype.

At Fueled Coaching and Nutrition, our goal is to help you achieve your goals in a fun, and science based manner.

From racing your first triathlon, to qualifying for Boston or the Triathlon World Championships, to racing with no GI distress or achieving your ideal body composition. We provide a step-by step system to achieve success.

You train hard, you’re dedicated and you believe you’re doing everything you need to to achieve your goals. But there is so much conflicting information on sports nutrition and training strategies. One day it’s high carb, the next it’s keto. How many hours a week should you be training for your Ironman? 10 hours or 20 hours?

It can be very overwhelming. Believe me, we understand the confusion this causes. That’s why here at Fueled Coaching and Nutrition we’re providing clear, easy to follow, myth busting information. Just the science, not the hype.

When you work with us, you’ll receive a road map to achieve your goals. Step one is deciding how much 1:1 or accountability you’d like. Are you a DIYer, want to be on a team, or you’d really like to have more 1:1 accountability? Any of the options are designed to provide you everything you need, and nothing you don’t. So you can just cut through the myths, the misinformation and get straight to the best nutrition and training strategies out there.

Get ready to have your best season yet, smashing your goals and having fun doing it!

Athletes’ Success Stories

Cristina has been working with me on developing healthy eating habits. We started off with a 3-day analysis to get a sense for how I eat and why. From there we developed a plan that is specific to my life and my goals. Cristina’s guidance has transformed my approach to food and is helping me achieve a healthier, more conscious life. I couldn’t be happier with my experience!


I have been working with Tina for about a month and she has helped me completely transform my diet for the better. With her help and encouragement, I’m exploring new healthier food options. First she did an in-depth diet analysis where she was able to identify some of the unhealthy choices I was making. Next she gave healthy alternatives using an index of recipes she has compiled. She continues to follow up sending emails with new recipes and foods I should try. She also has always been available via email, text or phone call if I have questions. The results so far have been great. Before working with Tina I was regularly experiencing GI issues and since starting with her my GI issues have ceased and I generally feel healthier.


I met Cristina in April 2011. I was looking for nutritional advice and help with my diet. I wanted to lose a little weight and increase my fitness. Cristina was so easy to work with. She did a thorough job of analyzing my nutrition and fitness. I really liked that Cristina listened to me and offered a realistic approach. No fasting or diets, just good information based on what I really eat and how to maximize my health and fitness through foods I like to eat. I found the experience life changing. Shortly thereafter I started endurance training with Cristina as well. Cristina remains my coach today. I highly recommend Cristina Caldwell to anyone looking for a skilled endurance and/or nutrition coach.


Tina was amazing to work with. As a busy professional and a single mom to an 11 year old, it was important to me to key into the factors that were stalling weight loss as well as performance. Having been an athlete for quite some time, I thought I had heard/analyzed everything. She highlighted areas that I hadn’t thought of and was able to give me new insight into why I was having certain cravings, etc. I never felt judged but found her analysis insightful, thorough and helpful. Tina was great about following up with me as well. I recommend her services without reservation & with highest praise!


Well…you nailed my nutrition…unreal! Thank you a million times! From the top down the plan was awesome/flawless! I felt pretty amazing all day and I know along with my training the nutrition played a major role…without this I don’t know that the result is the same; certainly not on the run. Thanks so much! It was awesome working with you on this!
