India Lee
India Lee is one of Britain’s leading professional long-distance triathletes and one of the most reliable performers on the global circuit.
A genuine all-rounder, she brings an elite front-pack swim, a smart and powerful bike leg, and a resilient, fast run. That balance makes her a constant contender across IRONMAN, IRONMAN 70.3 and T100 racing. In recent seasons, India has firmly established herself among the world’s best. She holds a top-three ranking in the T100 Triathlon World Tour and has claimed standout victories at the inaugural T100 Miami, IRONMAN Les Sables, and IRONMAN 70.3 Tours Métropole. She races with confidence on the biggest stages and delivers when it matters most — calm under pressure, ruthless when opportunities appear.
Off the course, India is known for her professionalism, authenticity and relentless work ethic. Her content offers a genuine insight into life as a professional athlete — from training and racing to travel and recovery — creating strong engagement and real connection with her audience. That credibility translates into meaningful value for partners.
Managed by Teresa Hamilton, India’s career is built around long-term, performance-driven partnerships grounded in trust, shared ambition and sustained success.
Arthur Horseau
Arthur Horseau is a leading French professional long-distance triathlete and one of the sport’s most resilient performers. Known for his strength in tough conditions and his ability to build races intelligently, Arthur combines a strong swim with a devastating bike leg and a fast, controlled marathon — a profile that consistently delivers results on the world’s hardest courses.
His breakthrough came in 2023 with 6th place at the IRONMAN World Championship in Nice, alongside wins at IRONMAN Lanzarote and Embrunman, both achieved with course-record performances. After stepping away from competition to address physical and mental challenges, Arthur returned in late 2025 and made an immediate statement — winning IRONMAN Cozumel off just ten weeks of training, securing qualification for the Kona World Championship and underlining his world-class potential.
Based in France and coached by Richard Laidlow, Arthur is fully focused on building towards a major 2026 season. He is widely respected for his professionalism, openness and work ethic, and is a proven, credible partner for brands looking to align with performance, resilience and authenticity at the very top of the sport.
Rebecca Anderbury
Rebecca Anderbury is a British professional triathlete based in Loughborough, United Kingdom, now in her third season racing at elite level. Having qualified for both the 2025 IRONMAN and IRONMAN 70.3 World Championships, she’s continuing to make her mark as one of the sport’s most exciting emerging athletes.
Rebecca is known for her powerful bike–run combination, particularly over the 70.3 distance, and has made huge progress in the swim over the past season — putting herself in a competitive position from the very start. Her 2025 season has already been packed with standout performances, including:
2nd – IRONMAN 70.3 Swansea (Pro Series)
4th – IRONMAN 70.3 Valencia
8th – IRONMAN Hamburg (European Championships)
She also made her T100 World Series debut in Spain, impressing with the fastest bike split of the day and showing she can mix it with the very best in the world. Rebecca’s combination of consistency, strength, and steady progression makes her a name to watch as she continues to rise through the professional ranks.
At TriSociety, we take a tailored approach to athlete management, combining industry expertise with a deep understanding of what it takes to succeed at the highest level. We work closely with our athletes to build sustainable careers, helping them thrive in and out of competition.
