The Marathon Project Names Blank’s Sports Nutrition As Official Nutrition and Personal Bottles Program Sponsor

April 16, 2025

The Flagstaff-based company offers original and customized sports nutrition products made by athletes, for athletes.

CHANDLER, Ariz., (April 15, 2025) /ENDURANCE SPORTSWIRE/ – The Marathon Project has announced its first major corporate partner. Race organizers have released the details of a multi-year agreement with Blank’s Sports Nutrition to be the event’s official nutrition and personal bottles program sponsor.

Blank’s Sports Nutrition was founded in 2024 by professional triathlete Michael Arishita in Flagstaff, AZ. The company offers a wide variety of sports drinks and gels at affordable prices and provides customers with the opportunity to create their own mixes. Athletes can customize their drinks or gels by selecting their flavor strength, carbs per serving, sodium, caffeine levels, and the maltodextrin-to-fructose ratio, choosing from a dozen different flavors.

Arishita said Blank’s believes sports nutrition should reflect the individuality of every athlete.

“We all have different needs and preferences in our sports nutrition, and we’ve built Blanks around that truth,” Arishita said. “We also believe that quality nutrition shouldn’t be so expensive. We’re here to make high-performance, personalized fuel more accessible—by athletes, for athletes.”

The Marathon Project had previously announced its revolutionary personal bottles program that will be available to all 1,200 athletes participating in its two marathons on December 20 and 21, 2025. It will be the largest such program in marathoning history.

Marathon Project CEO, Ben Rosario, said that Blank’s was a perfect fit for obvious reasons.

“In order for us to provide our participants the opportunity to run as fast as possible on race day, we need to give them access to the same sports nutrition products that they use in training,” Rosario said. “Essentially we believe that there is no one product that works for everyone and clearly Blank’s, with its customized mixes, feels the same.”

The Marathon Project and Blank’s will collaborate to educate athletes on the world of sports nutrition in the months leading up to the event. The two entities will release a series of videos, available to the public, covering proper fueling practices for training, racing, and recovery.

Arishita said every great nutrition plan starts with one question, “Where do I begin?”

“Our mission with the video series is to guide athletes through building a fueling strategy that’s personalized, tested in training, and optimized for performance,” Arishita said. “By the time they hit the start line in Chandler, their drinks and gels will be more than just generic on-course nutrition—they’ll be part of a customized plan built specifically for them.”

The partnership will culminate at The Marathon Project Expo on race weekend where anyone in attendance can visit the “Blank’s Café” to design their own drink and gel mixes in person, and have the Blank’s team create it right then and there to enjoy it for the race.
