"She is an incredible coach!"

Watch this video testimonial from Ironman Competitor, Matthew Garrett, to learn why he highly recommends hiring Mary as your triathlon coach.

I wanted to finish my second half Ironman. The first race was fine, but I guess the post race high and sense of accomplishment were working against me. As the euphoria waned over the course of six months, I found myself staring at my calendar and another half Ironman looming in six months. Six months turned into five and five into three. I was out of shape. Thankfully a friend recommended Mary. She was able to prepare me without me neglecting my work or family. Through the regular encouragement to the structured workouts, she got me to the finish line. I highly recommend her as a coach and as a friend.

As a beginner triathlete, the idea of taking on an Ironman 70.3 distance was very overwhelming. When I started with Mary, I had only completed 4 sprint triathlons and was very weak in swimming. My training partner and I decided to hire Mary in preparation for the jump to the 70.3 distance and it was the best thing we could have ever done! She developed a detailed 18-week training program that took me from swimming 1000-1500 yards at around 2:45/100 yards pace to swimming 2500-3000 yards at 2:10/100 yards pace. Her swim workouts were life changing! She took the time to do lactate threshold testing with us in the beginning so that we could focus on HR zone training early on. This paid off as the weeks went on and I saw my running pace improve by about 30 seconds per mile. Overall, her plan was built specifically for my goals, strengths, and weaknesses, and I went into race day 100% prepared. I felt strong for every minute of the half Ironman thanks to Coach Mary! Lastly, I was able to train hard for 18 weeks with ZERO injuries which is something I never thought would happen. If you are looking to jump to that next distance or even just get stronger/faster, Coach Mary is your girl!

​Mary is an excellent trainer and coach. She has a passion for fitness and sports and it shows in her work. Since working with her, my cardio has improved as well as my muscular strength and endurance. I am a CrossFit athlete and my sessions with her have greatly benefitted my athletic performance. I give her FIVE STARS. :)

I signed up for Ironman Texas in September 2017 and had no idea where to begin.  I looked for some plans on the internet and they were pretty vague.  Mary stepped up and said she would coach myself and another for this race.  Coach Mary made an appointment for me at the Athlete Development center at Texas A&M to determine my lactate threshold and then developed a very detailed training plan based on my heart rate zones. Mary was very involved in every aspect of my training and was diligent about creating a challenging and thorough training plan for 22 weeks.  Mary looked at each one of my completed workouts, provided feedback each time and held me accountable when I missed a workout without a valid excuse.  She was always available on a daily basis, when needed and she listened to my cares and concerns.  If you’re looking to do ANY distance triathlon and be pushed to do well, I’d HIGHLY recommend Coach Mary!

I have been training with Mary for 6 weeks now. She is teaching me a different style of running that has less impact on my back and knees that really helped me. I had tried it on my own, watching instructional training videos which were difficult to follow but Mary has a very effective way of describing the mechanics making it easy for me to incorporate into my running. She has a great positive attitude, always encouraging me on. A great coach, I would highly recommend her to anyone who is serious about their training. Be prepared to work hard!

I recently took Mary’s 21 day challenge and I highly recommend everyone doing it at least once! I learned so much about portion control and realized just how much I was overeating at every single meal, including snacks! What a huge eye opener! I also really loved the workouts! They were challenging yet not too hard and discouraging. My other favorite part was the constant support and leadership I got from Mary on our Facebook group. I loved having her to be accountable too when I couldn’t always do it for myself. I would definitely recommend this program to others and even take it again myself.

I’m a mom of two kids who, after 6 years, still haven’t shed all that lovely baby weight. I used to be the type that could literally eat anything and everything and never gain a pound. Dieting to lose weight was a completely foreign concept to me and I’ve never been a huge fan of working out. When I was introduced to the 21 Day Fix I was immediately interested because I didn’t have to “cut out” a lot of the things I like to eat. It focused more on the portion size. Not to mention, anyone can do a 30 minute workout! I could literally tell a difference in just one week. Not just on the scale but also in the way I felt. When you fill your body with good things on the inside, it’s only going to make YOU feel good on the outside! I would recommend this program to anyone!

After doing the 21 day fix with Shakeology, I lost 6lbs and had more energy than ever! Mary kept me on track by asking questions daily to hold me accountable. I never thought eating healthy and being active could be so easy! I have never felt so healthy or comfortable in my own skin as I did by the end of the 3 weeks. That motivated me to keep going!

Jenn W.

I feel great! It has been a rewarding journey for sure! 8 inches lost from waist, neck, chest, thighs, and bottom. About 6-8 pounds lost, and my clothes definitely fit better!

Jason W.

We had great results! He lost 8 inches and I lost 6 1/4!!!! We are super pumped and going to keep working We didn’t have a scale so we don’t know how much weight we actually lost…but we both FEEL better and our clothes fit BETTER!!!!

Jamie and Jason W.

Since I started doing the 21 day fix I cannot express how much better I feel. I was already working out but the eating plan helped make even healthier choices and Shakeology really helped with my daily headaches and increasing my energy level. It was not easy, but completely worth it! Thanks Mary Gilvary Timoney for getting me into it and helping keep me on track!!! I am happy to say I lost 10 lbs and 9 inches. My clothes fit a lot better meaning I can go shopping.  I feel a lot better and learned so much that I’m excited to continue what I learned. Now time to use this extra energy at work.

Holly T.

I lost just shy of 4 pounds. So I have less than a pound to go and plan to continue the fix for another week. Pictures to follow. Dug, dug, down deep in the storage drawers under my bed to find my size 4 pants; they fit perfectly, haven’t worn them since last spring. Thanks Mary Gilvary Timoney for getting me ready for my spring wardrobe. Looking forward to the next 21 Day Fix.

Leslie T.

Yay! I am so proud of myself for doing this challenge and sticking with it for the whole 21 days!! Thank you to everyone in this group for all of your encouragement and positive motivation! I truly feel better about myself and much healthier and motivated to keep going! I was 207 when I started the challenge, no energy, insomnia like crazy, and just completely out of shape. Today I am 182 lbs and a total of 6 inches overall lost. I truly have no sugar cravings, better flexibility, stronger in mind and spirit. Have some wonderful recipes from all of you to use in the future. It is a great start to my New Year, New me! Mary Gilvary Timoney you are a fantastic coach! You will have a successful future with your tri-athletes! You have truly changed my life! Thank you!
