SheriAnne Little

As the Head Coach at Next Level Endurance my goal is to impact as many people as possible and train new coaches about our philosophy to positively impact as many people as they can. First and foremost I am a mom of 3 young beautiful children.  I am a Fitness and Nutrition Coach that believes in helping people realize their untapped potential.  I believe too many people go through life wondering if and wishing they could do something magnificent. Everyone’s “magnificent something” is different, mine just happens to be epic adventures.  Everything I do I think about my children and the example I am setting for them.  Setting goals is critical to being successful in life and I love to set big goals that make my heart beat a little faster and make me wonder if it is possible because I love nothing more than busting past that mental barrier.  Anything is possible. As a mother of 3, a multiple World Champion qualifier and multiple podium finisher at Ironman events, I know what it takes to get it done, yet respect the importance of family and responsibilities when it comes to running a business.

Currently, I am striving to be the best version of me that I can be no matter what the athletic event is.   I have raced in multi-day expedition races, Xterra, Ironman, Ultra running, and Mountain Biking events.  Always striving to push myself to my next level and truly see what is possible for me.

I grew in Chicago and have lived in southwest Michigan for the past 10 years. I have three amazing kids who keep me quite busy on a daily basis. I am a self- described endorphin junkie, and when I’m not chasing after my children, or my puppy, my other passion is triathlon–primarily off-road triathlon.  In addition to training and racing, I teach various classes (spin, TRX, bootcamp, etc.) at a boutique fitness studio in my hometown, and I am a certified personal trainer, a USAT Level 1 certified coach and a Total Immersion Certified swim coach.

I do between 6 and 7 XTERRA races per season, with my final race in October at the XTERRA off-road World Championships in Maui. I have 5 World Titles to my name.  I am the current 45-49 and 4 X 40-44 age division women’s world champion.  I also do several mountain bike races throughout the summer and on occasion will throw in a trail race to keep me sharp.

Training can be grueling at times, but it keeps me sane and makes me a better person toward both my family and friends. It continually pushes me to limits I never thought I could reach. I love the physical and mental challenges triathlon presents. I hope to instill my competitive spirit and the importance of having a goal in all the athletes I coach. I truly believe that becoming fit is possible for anybody as long as they have perseverance.

Xterra Training

Coach Mimi has been an XTERRA Ambassador for the past 8 years.  She writes a bi-monthly article for the XTERRA Tribe newsletter, as part of the “Couch-to-XTERRA” program, which is geared toward the beginner off-road triathlete.  The training program is designed to do just what it says–help you get off the couch, into training and to the start of an XTERRA race.

Coach Mimi and SheriAnne have also helped intermediate and even advanced level off-road clients reach their respective goals–whether it be reaching the podium in a race or qualifying for Maui.  If you are interested in taking your off-road enthusiasm to a higher level, we promise you lots of mud, sweat and smiles.

Let us help you reach your next level!
