Cat Hulbert started gambling for a living 40 years ago. A blackjack player in her 20s, she became so skilled at winning money from casinos, she was soon very unpopular with them all around the US. Cat took up poker in the 1980s, and was one of the first women to break into the ranks of professional card players. The Game Show Network called her "the best female gambler on earth." Now retired, Cat says she is not sure that she would legalise gambling in a state that did not have it, as it can ruin so many lives.

Megan Harrington-Johnson doesn't let worry and doubt stop her when she wants to complete a 13km open-water swim. The South African endurance swimmer has swam in shark infested waters, even though she's petrified of them and has had a close shave with a Great White. Megan says she's often the only woman on the team, but thinks it's fear rather than ability that holds other women back from doing what she does. Sweating in the water is an issue and Megan talks about the importance of staying hydrated and eating lots of calories to get through a big swim.

Manu Vilaseca started by running 5km races and now does 160km ultra-marathons. The lengthy courses are rarely on flat terrain, they're normally up and down mountains and the conditions can be unpredictable, but Manu, who's from Brazil, says even when her mind is telling her to stop she knows how to talk herself round and get through. The competitions might be punishing on Manu's body, but she says she loves the feeling of total exhaustion and almost craves the pain she will feel afterwards so she knows she's pushed herself to the limit.

Maria Toorpakai grew up in the traditional tribal region of Waziristan, and from an early age decided she would rather play with the boys than stay inside with the girls. So she burned her 'girly' clothes and cut her hair short so she could run and jump and wrestle outside. When her family moved to Peshawar Maria picked up a squash racket for the first time, and by the age of 16 was Pakistan's number one player. Her success led to death threats however, and she was forced into hiding and playing only in her bedroom. Maria now lives and trains in Canada. Her book A Different Kind of Daughter: The Girl Who Hid From the Taliban in Plain Sight (with Katharine Holstein) is out now.

Malaysia's Nicol David has dominated women's squash since 2005. She was the World No 1 woman player for an unprecedented 9 years.

She started playing squash with her sisters to work out her hyperactivity, and quickly became a junior champion. She says squash is like 'physical chess' - you are always thinking ahead by two or three moves.

Hafsat Mohammed is a Nigerian peace activist who survived a Boko Haram attack on a bus and works to combat violent extremism in the country by engaging young people at the grassroots level. She brings Christian and Muslim communities together to find ways to stop young people joining radical groups. Hafsat says when she was growing up this was a peaceful part of the world and it makes her sad that there is so much hate and violence there now, so she's made it her mission to stop it, despite threats made against her.

Gulalai Ismail remembers being young and seeing graffiti chalked on the walls of her home town Peshawar, in north-west Pakistan, calling for young men to join violent extremist groups. As a teenager Gulalai started campaigning for the rights of women and today has broadened her activism out to include anti-radicalisation programmes, and projects dealing with HIV/AIDS education and safe abortion. Gulalai, who has won many awards, has been threatened because of the work she does and had to flee her home after an attack a few years ago.
