Paralympics day 4: Tatyana McFadden begins gold rush, Brazil has new heroes

    (CNN)Day four of Rio 2016 saw another 54 gold medals on offer.

    Tatyana McFadden continued her quest to win a medal in every race she's entered... and there's seven of them.
    There was plenty to cheer for Great Britain on the water this morning as it totally dominated, and host nation Brazil had no less than four new heroes in the Olympic Stadium.

      Seventh heaven?

        The superstars of the Paralympic season are often lauded with recourse to their Olympic counterparts.
        Versatile swimmer Daniel Dias is known as Brazil's answer to Michael Phelps; Jason Smyth, the fastest Paralympian of all time, is sometimes called the 'Irish Usain Bolt.'
        But from a Soviet orphanage to her twelfth Paralympic podium, wheelchair athlete Tatyana McFadden isn't served by commendatory comparisons. As IPC president Sir Philip Craven rightly contends, "Tatyana is great enough already."
        Born with paralyzing congenital disorder Spina bifida, McFadden spent the first six years of her life in Russia walking on her hands.
        Left in an orphanage by her mother, her health deteriorated and doctors feared she wouldn't live long.
        That was until she met Deborah, the American visitor who would go on to adopt her.
        Sport was Tatyana's salvation.
        Two decades on, having been brought up to believe she can overcome any obstacle, the 27-year-old is competing in every Rio 2016 wheelchair event from the 100 meters to the marathon.
        Such is her talent and determination, she could leave Rio with seven medals.
        Already with silver to her name from the T54 100m -- supposedly her worst event -- McFadden added 400m gold Sunday, finishing comfortably ahead of compatriot Cheri Madsen and China's Lihong Zou.
        Hannah McFadden, adopted from Albania, was born without a femur in her left leg. Competing side by side in three events, the McFaddens could become the first sisters to finish side-by-side on the podium in Paralympic history.
