Rosecler Costa's Mission to Pave the Way for Women
With 30 years in triathlon, the 'Ironmãe' uses her experience to welcome beginners and ease the endurance journey.
Triathlete and coach Rosecler Costa transformed three decades of challenges into a personal mission to inspire and welcome women into triathlon. By leading female teams and teaching everything from open-water swimming to gear selection, she strives to make endurance sports accessible and eliminate the fear of the unknown.
Taking on triathlon for the first time can be intimidating, especially for women who find few role models or welcoming spaces when starting out. For Rosecler Costa, who brings about 30 years of experience to the sport, bringing more women into endurance athletics has grown from a coaching job into a true life mission.

Shortening the Path and Breaking Barriers
When she took her first strokes and pedal turns, Rosecler faced an environment with virtually no support: without accessible guidance, her daily choice was learning through trial and error or giving up entirely. The uncertainty and burnout of having no one to turn to shaped her journey, inspiring her commitment to spare future generations from those same obstacles.
Her mentorship goes far beyond handing out training spreadsheets. In practice, it means guiding athletes who have never set foot in open water and demystifying gear selection and race routines. For Rosecler, answering questions without judgment lets beginners adapt to the sport within a few years, building the independence and confidence needed to cross their own finish lines.
