Voted by ESPN as the Greatest Endurance Athlete of All Time

Aspiring to reach your personal peak performance requires extreme discipline, commitment and respect for all aspects of training—including recovery and replenishment.

At the height of his athletic career, Mark enjoyed crossing the finish line first, time and time again, for the hardest and longest endurance races in the world. He was voted "The Greatest Endurance Athlete of All Time" by ESPN and inducted into the Ironman Hall of Fame.

What we think is just as cool is that Mark continues to strive for excellence in everything he does. Through his company Mark Allen Sports, Mark coaches and advises both elite and amateur athletes around the world. Impressively, Mark continues to personally train every day (surpassing anything we mortal humans could do) and he always finds time to strike a balance with recovery, restoration and refueling.

Athletes Need to Replenish, Rebuild, Repair

"Staving off fatigue during training is an absolute key to being able to increase fitness and performance. And when I talk about fatigue, it is both the physical capacity of your body to sustain a solid effort in workouts, as well as your ability to mentally stay on task with both training and work.

When the day is done, the real work begins where your body has to replenish, rebuild and repair all the systems used during the day. The supplement market is flooded with products claiming to target performance, but ignore deep recovery. The products I am using from Tennant Products are working at the very deep cellular level to enhance all of those recovery processes. From training to recovery it’s THE best I have ever experienced."

Muscle Recovery and Brain Clarity

"Overall there has been a dramatic physical and mental transformation in my ability to train, work and recover. Restore has enabled me to basically double my workout time, without my muscles fatiguing like they used to. Brain Food helps me to have a quiet focus all afternoon, when normally there is a big dip in my ability to stay on task."

~ Mark Allen, the GOAT of Ironman Champions

It’s your body. It’s your life. Ingredients matter.

"Before my main workout, I take Restore Professional and Raw Materials, and sometimes Neo40 Professional. Then I take Brain Food in the afternoon."
