The youngster, who trains in Bonnybridge and Denny with Fudoshin Karate Club, has every chance of being fast-tracked to the top after a stunning medal haul over the past three years in the sport.
In the past two months she has landed the gold medal in both the British International Open Championships in Sheffield and the Scottish Championships, plus a gold and bronze in the Scottish junior championships where she fought in the under-16 age category, triumphing in both.
And 13-year-old Carly has been training with the Scottish national team for around 18 months and will try out for a place in the national team when she turns 14.
She has also been selected to go and try out for the British Athlete Talent Programme to identify potential athletes for the 2020 Tokyo Olympics and start working within the British National team immediately.
In 2015 McNab landed 10 medal positions including four gold, from 12 competitions and this year she has gone even better with 11 out of 12 and eight on the top of the podium.
She is now undefeated in her age category since June with two competitions remaining this year, and coach Craig Penman hopes to better even this incredible record next year with Tokyo 2020 in sight.
