The 16 year-old lifted the NABC Championship crown at 60kg last Sunday in Bristol courtesy of a unanimous points decision against Jess Wrighton, of South Cheshire ABC. Whitwell dominated from the opening bell before really showing her class in the final round with a series of big shots. It meant she followed up her success in the equivalent NABC event at 63kg last year when she also scooped the Junior Novice Championships title. And she will now step up to youth level next month on a high. Whitwell said: It was great to win the title and Im very proud of the success Ive had in the last year. Ive put a lot of work into training and its been tough as Im at college and also working part-time. Its going to be really hard for me stepping up to youth level as Ill be fighting who are older and more experienced, but Im looking forward to it. Whitwell, from Bluntisham, will aim to continue her wave of success in the National Youth Championships in February. Before then she could feature in the Golden Girl international tournament in Sweden alongside her older - and equally as successful - sister, Shona (19), who is in the England squad. Father and trainer Steve Whitwell said: To win three national titles is quite an achievement. Harli had a nasty arm injury earlier this season when she tore a bicep muscle and it her a long time to get over it. But she has come back really well and, just like Shona, she has a bright and exciting future ahead of her.
