Capriroso and the Portland Marathon Partner to Deliver the Future of Endurance Preparation

June 5, 2026

New Partnership Helps Athletes Make Smarter Training, Recovery, and Performance Decisions on the Road to Race Day

PORTLAND, Ore. (June 5, 2026) /ENDURANCE SPORTSWIRE/ — Capriroso, the Biological Intelligence Engine helping endurance athletes train, recover, and perform more effectively, today announced a partnership with the Portland Marathon as the Official Training App and Performance Partner of the 2026 Portland Marathon.

The partnership introduces Portland Marathon participants to a new approach to endurance preparation built around biological intelligence, helping athletes make more informed decisions throughout their training journey and arrive at the starting line better prepared for race day.

With more than 15,000 participants expected at the 2026 Portland Marathon the partnership marks an important milestone for Capriroso as it expands its presence within the endurance sports community.

“Most athletes don’t need more data. They need more clarity,” said Chad Eubanks, Founder and CEO of Capriroso. “Wearables, training platforms, and health apps have created an abundance of information, but information isn’t intelligence. Capriroso helps athletes understand what their biology is telling them, what their body is prepared for today, and what actions will best support their goals. That’s the future of endurance preparation.”

The partnership with the Portland Marathon reflects a shared belief that marathon preparation is about more than following a plan. Success is built over months of training, recovery, nutrition, lifestyle management, and thousands of small decisions made along the way.

“Every event asks a different question of the human body,” said Michael Marckx, Co-Founder of Capriroso. “Preparing for a marathon isn’t simply about covering the distance. It’s about preparing for the specific demands you’ll face on race day. Our vision is to help athletes train for the race they are actually running, not just the miles they’re logging.”

Capriroso allows athletes to connect their wearable devices, identify a goal event, and receive adaptive guidance informed by physiology, recovery status, training load, performance readiness, and lifestyle factors. As an athlete’s condition changes, Capriroso continuously updates its recommendations to help guide decisions across training, recovery, nutrition, strength, and mobility.

Unlike traditional training platforms that focus primarily on tracking workouts or managing schedules, Capriroso functions as an intelligence layer between athletes and their data, transforming biological signals into clear, actionable guidance.

“We’re excited to team up with Capriroso to provide our athletes with a new way to prepare for their race,” said Aubrey Curl, Director of Partnerships for the Portland Marathon. “Capriroso offers innovative training solutions with clear daily guidance that gives runners a smarter, more personalized path to the starting line. We’re excited to introduce that capability to our community.”

As endurance athletes increasingly seek more personalized and adaptive approaches to performance, the partnership between Capriroso and the Portland Marathon reflects a broader shift toward preparation that is more individualized, more responsive, and more closely aligned with the unique needs of each athlete.
