Brownlee Fitness Expands to the USA

August 13, 2025

The move will bring the Brownlee Fitness signature world-class triathlon and multi-sports coaching and community across the Atlantic

Leeds, UK / Colorado, US (August 12th, 2025) /ENDURANCE SPORTSWIRE/ – Brownlee Fitness, the triathlon coaching community founded by Olympic and World Champion brothers Alistair and Jonny Brownlee, is officially launching in the United States. With this expansion, U.S. athletes can now join the Brownlee Fitness Squad and community with direct support, and coaching, with operations based out of Colorado, U.S.

Rooted in the training methodology of two of the sport’s most accomplished global triathletes, Brownlee Fitness offers real, human-led coaching, not algorithm-based plans. Athletes gain access to personalized support tailored to their lives, goals, and experience levels—from first-time triathletes to seasoned competitors.

Jonny Brownlee, Founder of Brownlee Fitness said: “We’re incredibly excited to bring Brownlee Fitness to the U.S. Over the past 25 years, we’ve developed and refined a training philosophy that helped me and my brother Alistair win five Olympic medals and a fair few Ironman victories. Now, U.S. triathletes can tap into that same approach to reach their own goals. At the heart of Brownlee Fitness is our deep belief in community —supporting and motivating each other on every step of the journey. Our members share a passion for sport, for being active, and working towards their goals

US-Based Team

Leading 1:1 coaching in the U.S. and based out of Boulder, Colo., is Laura ‘Sid’ Siddall, a British professional triathlete and experienced coach known for her athlete-first approach. While Siddall focuses on individualized coaching, U.S.-based consultant Melanie Mitchell will support Brownlee Fitness with strategic communications, brand development, and community engagement initiatives, helping shape the presence of the Squad community from the Colorado hub.

Brownlee continues, “At this stage in my career, I really enjoy leading this community and helping others achieve their potential. Whether it’s answering a question about how to pack a bike for your first overseas race or shaping personalized training programs, I’m here to support athletes, alongside coach Sid in the U.S. and the team in the UK.”

Laura ‘Sid’ Siddall, US Coach at Brownlee Fitness said: “I’m really excited to join Brownlee Fitness, support the Squad and help bring an incredible multi-sport community to the U.S. Jonny and Alistair have always believed in making sport and triathlon accessible and fun for everyone. Looking back at my own journey in the sport as a complete beginner as an expat working in Australia, it really was the community and group support that drew me in. I’m looking forward to helping athletes of all levels find that balance, work toward their goals, and really enjoy the journey along the way.”

Brownlee Fitness also plans to bring its signature training camp model to the U.S., offering immersive experiences that combine expert coaching, hands-on support, and connection with fellow athletes —complementing its successful European camps.
