From the tennis court to the boxing ring, the athletics track to the football pitch, the visibility of women in sport has been gathering pace. Women's competitions are increasingly popular. In Roar Sam takes a deep dive into the experiences of some of sport's most high-profile female athletes - some have overcome heartbreaking adversity to reach the top of their game; others have succeeded in the face of prejudice. Like Sam, all have been propelled by sheer grit and determination to succeed. Many now campaign for women's equality and acceptance in sport, knowing the confidence it can bring young girls and the message that they can achieve anything. Featuring a series of candid interviews from some of sport's most successful women, Sam lifts the lid on what it takes to reach those heights: from coping with puberty to foregoing teenage fun to pursue a dream; from the punishing physical training schedule to the mental power needed to win or bounce back from defeat; from the pressure of the media spotlight to the challenge of competing as a new mother. And, what it feels like in that magical moment when you step up to the podium knowing every sacrifice has been worth it. Roar is a celebration of the bold and fearless - the women empowering future generations to follow in their footsteps - but it is also an inspiring look at how sport can change lives and challenge society.

Sam Quek is mainly known for her starring role in the 2016 Olympic gold medal winning hockey team. This was the first time a British ladies team had won gold, but what is much less known is that Sam's rise to the top of her spot was far from easy. Sam missed out on being part of Team GB at the London 2012 Olympics but competed for England at the 2013 EuroHockey tournament and 2014 Commonwealth Games, which she won silver medals. She won the gold at the 2016 Rio Olympics after the GB hockey team beat the Netherlands on penalties. How Sam overcame the bitter disappointment of being overlooked for the two previous Olympics and ensured that she wouldn't miss out again are revealed here for the first time. She also tells of her tough childhood and her battle to reach the heights that she has. She then went on to further fame by appearing in 'I'm a Celebrity' where she proved to be hugely popular with the viewing public, eventually finishing fourth. Sam now presents a variety of sports for TV, including men and women's football, NFL and hockey. She has been signed up to be the main presenter for the women's World Hockey Championships in 2018, held in August. She is hugely popular on social media with thousands of followers on twitter and instagram. Sam also has some very strong views on how women are portrayed in sport and their treatment by both coaches and the media. This is a hugely topical subject at the moment and promises to remain so for some time.
