March 21, 2023

Rinny's roster has limited availability, and Tim & Rinny's World is open to all.

DALLAS, TX – March 21, 2023 /ENDURANCE SPORTSWIRE/ – Mirinda (“Rinny”) Carfrae and Tim O’Donnell announced the launch of their coaching business that will leverage TriDot’s Optimized Triathlon Training®, technology driven by data and artificial intelligence. Their coaching business will focus on triathlon enhancing the lives of athletes through proper life balance, adventure, and family.

“I’ve had so many wonderful coaches over my career in triathlon, and now I want to give back to the athletes in the sport that gave me so much,” says Mirinda Carfrae, 4x IRONMAN World Champion who recently announced retirement from professional triathlon racing. “Leveraging the world’s best training technology, TriDot, allows me to spend my time doing what appeals most to me about coaching, which is to guide and support athletes.”

Rinny is opening her 1:1 coaching roster to a limited number of athletes. All triathletes are welcome to be part of Tim & Rinny’s World, which offers TriDot’s top-tier training functionality, interaction with Tim & Rinny through exclusive social media groups, periodic virtual and in-person events, and access to Tim & Rinny’s partner discounts. Learn more about either option by visiting their website. Tim will continue racing this year and will not open his roster until after this season.

TriDot delivers Optimized Triathlon Training® powered by data & artificial intelligence that produces better results in less time.

In 2022 alone, TriDot was featured in Forbes, Tech Times, Triathlete magazine, Men’s Journal, NY Weekly, and LA Weekly.

Originally from Australia, and now residing in Boulder, Colorado, 4x World Champion Mirinda “Rinny” Carfrae is a one of the world’s most recognizable triathletes. Rinny was a threat at every race she entered. In 2023, she retires as one of the greatest triathletes of all time, with over 50 wins at major events throughout the world and seven podium performances at the IRONMAN® World Championship in the span of a decade. Rinny’s passion for the sport will shift to coaching with TriDot, allowing her to connect with new athletes on an innovative platform that uses technology to optimize feedback on training and racing for fast results.
