The hunt for BT’s Action Woman of the Year 2015 is underway and every month BT Sport will be highlighting potential contenders.

But it’s not just down to us – we want you to nominate the sportswomen who have impressed you most, using the #ActionWoman hashtag on Twitter.

At the end of the year, 10 nominees will make the final shortlist and it will be up to the public to vote for who they want to succeed 2014 winner Charlotte Dujardin as Action Woman of the Year.

Lizzy Yarnold

Lizzy Yarnold added World Championships gold to her collection of medals

Lizzy Yarnold is on holiday. A stunning achievement in itself, given the recent (ice) track record of Britain’s most illustrious Winter Olympian. But the performance for which the 26-year-old athlete created headlines in March was of a more strenuous nature. She won the Skeleton World Championships in Winterberg to complete the Grand Slam of major titles in her sport. It is a measure of her towering success that the word ‘skeleton’ is now widely known to be a headfirst 90mph perilous pelt down an ice chute as opposed to anything dug up in graveyards.

Deservedly, having produced a record-breaking run to add World Championship gold to her Olympic, European and World Cup titles, she is taking a break. “It’s all I ever wanted and I need a few days of not talking about skeleton or ice or anything really.

“Winning the World Champs was incredible. I think it was a mixture of all of my family being there to support me and the fact that it had been a long, hard season and it was the last race, the relief was amazing!

“Also, because I set it as my goal for this season, after winning in Sochi I wasn't sure where my motivation would come from. In a way, the World Champs gave me the desire to keep going after such a high. Without it I'm not sure I could have gone into each race with the desire to win that I did. So having it on the mantelpiece to complete the set is pretty cool!

“We're just finishing all of our end-of-season reviews at the moment and then we get April off to have a holiday - I really can't wait! Last year my 'off-season' was so busy making the most of the Sochi excitement that I really feel like I need a break this year. I'm looking forward to catching up with my family and boyfriend James - they will be sick of me being around so much now I'm sure!"

Heather Watson

Watson beat a top 10 player for the first time this month

Heather Watson is becoming something of a regular in our Action Woman nominees. The British number one, who has climbed to number 41 in the world, this month makes the shortlist after notching up her first win over a top 10 player, defeating world number seven Agnieszka Radwanksa in straight sets in the third round of the BNP Paribas Open in Indian Wells.

Despite her tournament being ended in the last 16 by Spaniard Carla Suarez Navarro, the win marks a real step forward for Watson as she continues her new confident attacking style of play. Having not taken a set off Radwanska before, she was the picture of calm and poise as she served out the match to love to secure what is possibly the biggest win of her career.

“Aga is a fantastic player,” said Watson afterwards. “She has beaten me pretty comfortably every time before so I knew I was going to have to bring my A-game and play my very best. And that’s what I did.”

What makes Watson’s recent form all the more impressive is the difficult 18 months she had previously. Watson was diagnosed with glandular fever in April 2013, which saw a long road back to full recovery. After dipping down the rankings and struggling with her comeback, the 22-year-old has started to show her true potential since the start of the year.

“The tough times I went through have definitely made me stronger,” she said. “I have learned so much about myself as a person by pushing through any obstacle or struggle that has come my way. Those moments have actually helped get me to where I am today.”

It’s this mental toughness, along with a more aggressive game, which has seen Watson enjoy a successful start to 2015, winning her second WTA title in Hobart in January and she can look towards the grass court season with excitement and confidence.

Zoe Gillings-Brier

Gillings-Brier took to the podium twice in quick succession in March

Fearless snowboarder and adrenalin junkie Zoe Gillings-Brier took to the podium twice in quick succession in March after scooping medals at the Snowboard Cross European Cup competitions in Lenk, Switzerland.

Gillings-Brier, 30, claimed bronze after a tense photo finish and produced a near-perfect showing to secure gold just 24 hours later.

“I’ve been training in freestyle this winter but I don’t compete in freestyle, I compete in snowboard cross. It’s similar to motor cross except we’re on boards!” laughed Gillings-Brier. “There are lots of crashes, really unpredictable, it’s a fantastic spectator sport.

“Some of the jumps are pretty huge and you’re going in at around 50mph with five other athletes right next to you. It’s not a sport for the faint-hearted; you’ve got to be pretty brave and competitive to do it."

She added: “I’ve had so many injuries over the years but it doesn’t stop me from getting back out there on the snow. I once broke eight bones in my foot all in one go, plus I've had concussion, torn ligaments in my knees, shoulders, broken collarbones etc - the list is endless.”

“You’ve got to really look after your body and I’m careful about with my diet, training and the supplements I use. You're training at altitude in all sorts of weather so it can be pretty tough when you're out there at -25. I use Nutrition X to help ensure I've got the protein and energy to train and compete in the biggest competitions. Now the season is coming to an end I'll be heading back to the gym to prepare for next year."

Gillings-Brier finished in ninth position at the 2014 Winter Olympics in Sochi and, as Britain’s number one snowboard crosser, she already has her sights set on Pyeong Chang 2018, her fourth Olympic cycle.

This time she hopes her mum will be overcome her fears to watch her ‘little girl’ in action. "She flew all the way to Canada and ended up hiding behind the seats. Hopefully she'll be calm by the time the next one comes around!"

Nina Carberry

Carberry enjoyed success at the Cheltenham Festival

It’s a sport where men and women compete against each other but very few women make it to the top of National Hunt racing. Nina Carberry is one of the best. Beating the boys is not unusual for 30-year-old Carberry but a win at the Cheltenham Festival - the Olympics of horse racing - is the stuff of dreams for any jockey good enough to even get there.

When Carberry and her horse romped to victory in the Foxhunter Steeplechase she described it as “an unbelievable feeling - the highlight of my season so far”.

Carberry has been riding racehorses from the age of 10, rode her first winner at 18 years old and won the Irish Grand National in 2011. Born into racing royalty - her father won the Grand National in 1975, whilst her brother won it in 1999 - rumour has it the Carberry kids could ride before they could walk and she describes growing up in a family mad about racing as “a great craic”.

Three years ago Carberry enhanced her pedigree further by marrying Ted Walsh Jnr- brother to elite jockeys Ruby and Katy Walsh. Carberry claims that she and her husband try not to talk about racing when they are together but admits that family holidays often consist of a trip to Galway horse races.

Carberry is also having success as a racehorse trainer but her lifelong ambition is to win the Grand National at Aintree – which would make her the first woman to do so.

Bethany Firth

Six years ago, Bethany Firth wouldn’t go anywhere near water because of a childhood trauma. Now she’s a gold medal-winning, world record-breaking swimmer.

In March, the Northern Irish 19-year-old smashed three world records at the International Para-Swimming Meet in Glasgow, finishing the 100m breaststroke in 1.14:40, the 200m Individual Medley in 2.22:14 and touching in at 1.04:70 in the 100m backstroke before having to pull out of the finals due to a migraine.

The London 2012 gold medalist is no stranger to setbacks, with her mother Lindsey describing how she became terrified of water when she was two years old: “She fell right backwards into the deep pool, and after that she wouldn’t go near water. Absolutely petrified of it. I mean my husband’s a Baptist minister – she couldn’t even watch a baptism because she thought her daddy might drown.”

After enrolling at a special needs school where water safety was compulsory, Firth overcame her fear and excelled.

Now aiming for Rio 2016, she’s also keen to help others along the way. Her mum described what happened when she broke a world record alongside Hannah Russell, a partially sighted swimmer.

“She knew Hannah couldn’t read the numbers. She went over and she goes, ‘Hannah you got the world record’. She didn’t say ‘I got a world record Hannah’, it was you’ve got the world record.”

No ordinary swimmer, Firth suffers with memory loss - she can learn moves one day and forget them the next, sometimes painting her big toe or drawing a star on her hand to remind herself what to do in competitions.

“She was just flying,” Lindsey said of her daughter in Glasgow’s Meet. “Until you actually stand there and think about the size of what she’s done - it’s just amazing."
