"I was a fan of Marni and Karel from following Marni's blog and reached out to them last year regarding a training plan. I couldn't have been happier. First, they took a lot of time to discuss the options with me--something they didn’t have to do as I was not a coached athlete nor had I purchased the plan. Second, once I decided to purchase the half IM plan, knowing the timing of my race, Marni emailed me to ask if it was okay if she wrote in a few more weeks so the timing worked better with my races (at no extra cost). All that is nice, but did it work? Definitely, 22 minute PR and hit my goal for my HIM. Marni and Karel know and love the sport and it shows in all their interactions with athletes--so pleased that I am now a one-on-one coached athlete in 2016!!" -- Richie Favata
" Marni is always eager to help and her positive energy is contagious. Marni is truly a blessing in my life and I am so grateful to have her as my coach."
-- Cindy Stellmach
"I signed up for my first ironman and needed a solid plan. In an attempt to improve on my bike, I purchased the Trimarni bike workout plan (I love training on the trainer during the week). I then received an email from Marni asking about my goals - and that was the start of the many conversations we were to have the next few months leading up to my race. After my first phone call with Marni, I wished that she had one more space to coach an athlete...but since she didn't, I settled for the Ironman Plan and some phone consultations. What Marni gave me was so much more than what I paid for - she gave me a solid training plan, guided me to choose the races I needed to do prior, and more importantly, the confidence that I can finish an ironman. Through her plan, I was able to focus on training "smart" - I was able to dial-in my nutrition, stay healthy, and more importantly, be confident and strong up until and during race day. She helped me finish the race, while having the best time I have ever had! Marni and Karel are the best at what they do and won't hesitate to recommend them to people I know. If you want result, there's no need to look further!I PR'd the olympic distance by 30 minutes and finished my first ironman. More importantly, I was healthy and injury free all season". - Angelie Janseen
"My transition to Trimarni coaching was super. Marni and Karel assessed my fitness, assisted me with an annual training / race calendar and then discussed with me how we would progress with training and racing for my first year training with Trimarni. Very impressed with their one on one coaching. Always available to discuss my training needs and very helpful in taking me to that next level of my performance. Karel is great. His cycle background helped me understand the bike portion of triathlon racing. I have made enormous improvements on the bike. If you want the best bike fit, make an appointment with Karel. He fine tuned my bike position using his vast experience as a cyclist and bike expert. You know you are in great hands when you see Karel fitting professional athletes. I am riding stronger than ever. Marni's and Karel improved my running. I came to Trimarni Coaching with a nagging injury/limitation to my run performance. With their help, I smartly healed from the run injury and my run training progressed and now I am running stronger than ever.
Trimarni camps are great. Specific detailed camp schedules are provided to the campers. Successful athletes/speakers brought into camp to expand your knowledge as a triathlete. Yes, strong tough well thought out training with an explanation of the training methods. It is great to meet so many like minded triathletes at the Trimarni Camps. I look forward to finishing off my 2nd season with Trimarni and continuing on for a great 2017 as a Trimarni athlete." -- Jim Nitz
"I purchased a TriMarni prebuilt Ironman plan to get ready for my first Ironman. As I used the plan, I felt more and more prepared and ready both physically and mentally to have a great race day experience. I loved the addition of the strength plan as well. It helped me feel strong and durable, solid and ready for race day. Marni and Karel were great to work with and very knowledgeable! And now I am a Trimarni one-on-one athlete and learning how to train and race to my full potential." - Lisa Comer
"I approached Marni for some help with my fueling strategy for long course triathlon. I knew that I didn't have a repeatable approach and I needed something to practice in training and further test out at Ironman Mont Tremblant. I now have a detailed plan that Marni developed that supported my efforts to a Full distance personal record and left me feeling great at the finish line. The smile and the happy stomach are all the proof I need that this strategy gives me an incredible foundation to build upon. Thanks for the brilliant help!" - Dr. Christopher Morales, PT, ATC/L
"Six weeks from my Ironman race, I decided to obtain a new or better way to fuel my body for training/racing and needed help with my issue with cramping. So, I signed up to use Trimarni One Hour Consult and Race week Nutrition Service. With my limited time with Marni, she quickly provided me with a detailed nutrition plan, she assessed my current nutrition plan and gave me useful tips on hydration, nutrition, and recovery. I found her to be a very knowledgeable and inspiring person. Her race week nutrition plan was very detailed, but easy to follow and now I'm more knowledgeable and have a solid platform for future training/racing. I believe with her invaluable help, I was able to accomplish my goal- PR for my iroman race. For those who want to finish well, I highly recommend using Marni services." -- Larry O'Rourke
