Imagine centering your entire life around one goal—representing the United States at the Olympics—and dedicating four years of tireless work through good days and bad to achieve it, only to have success ripped away in the last moment. And then, somehow, getting right back up and starting the process all over again.

That’s the story of former Col. Zadok Magruder High School wrestler Helen Maroulis, who is participating in the 2016 Summer Olympics in Rio de Janeiro next month four years after a disheartening defeat to Kelsey Campbell in the 2012 U.S. Olympic Team Trials final.

Maroulis, who has been open in recent media interviews about her struggle to fully let go of the anger and forgive herself for the 2012 setback, has risen to female wrestling world dominance and, as a first-time Olympian, could be a gold medal favorite in the Rio games, from Aug. 5 to 21.

Maroulis joins two other Montgomery County natives who will be representing Team USA in Brazil along with their more famous teammate, Bethesda’s Katie Ledecky, who shot to stardom after winning a gold medal at the London games in 2012. Here’s what you need to know about these three first-time Olympians:

Helen Maroulis, women’s freestyle wrestling

  • Age 24; 5 feet 3 inches tall; started wrestling at age 7.
  • 2015 World Champion (three-time world medalist, overall); six-time U.S. Open champion
  • Hasn’t lost an international match in over a year; enters Rio on a 57-match win streak.
  • Most of her dominance has come in the 55-kilogram weight class. But to accommodate the addition of two weight divisions for this Olympics, United World Wrestling eliminated her class, forcing her to drop to the 53-kilogram division and adjust to her new frame.
  • Won all five of her Olympic Trials matches, outscoring her opponents, 55-2.
  • Her toughest opponent in Rio will likely be Japan’s Saori Yoshida, who has won three Olympic gold medals and 16 world-level championships.

  • Won 2012 Olympic Trials, but was beaten by Darnestown native and Bullis School graduate Caroline Queen, who earned the U.S. its boat, in the selection process by a technical tiebreaker.
