Marta Sánchez (Barcelona, ​​​​1995) has made a name for herself among the strongest women in the world. When she was little, she spent a lot of time in the water doing synchronized swimming. Now she does the same, but in a completely different discipline: now she swims hard in one of the three stages of the Ironman, the famous triathlon races that consist of swimming 3.86 kilometers, cycling 180.25 kilometers, and running a marathon (42.2 kilometers).
