Roots in Mexico and an active childhood

Aline looks back on her childhood in Mexico, shaped by a busy schedule of ballet, flamenco, and jazz classes, alongside playing baseball with her family and spending years in scouting.

Transitioning from dance to running and discovering triathlon

After stepping away from dance as a teenager, Aline casually took up running in Ibirapuera Park and spent some time training in CrossFit. A desire to ride on the road led to an unexpected purchase of a time trial bike, which served as her gateway to learning how to swim from scratch and building a steady journey in triathlon racing.

The 70.3 World Championship experience in Finland

In her very first half-Ironman race in Florianópolis, Aline earned a surprise qualifying slot for the World Championship in Lahti, Finland. Navigating the shock of qualifying, dealing with imposter syndrome, and having elderly family members travel to support her made the race a turning point in her commitment to the endurance lifestyle.

Athletic identity and women's presence in sports

The conversation dives into what it means to embrace the identity of an athlete regardless of performance level, as well as the role of inspiring other women. Aline stresses the need to push back against social media instant gratification, emphasizing that sustainable progress in endurance racing requires patience, consistency, and honoring every stage of training.

Entrepreneurship and the Blue Line rebrand

Blending her background in design with her passion for sports, Aline created custom frames to showcase medals, race courses, and finish times. The entrepreneur explains the transition from the former AA Sports to Blue Line—a name inspired by the blue line marking the shortest path on marathon courses, symbolizing every runner's pursuit of their own journey.

Sports marketing, authenticity, and brand building

Drawing on her sports marketing experience at Polar, Aline breaks down branding strategies across the endurance world and the importance of forging genuine connections with audiences. She highlights the value of seeking inspiration outside the sports bubble and avoiding hollow trends to build purposeful positioning with real identity.
