THANK YOU SO MUCH...on Saturday 10th October at the National Community Fitness Awards I won “Best Regional Instructor (North East)” and then went on the get “UK INSTRUCTOR 2020” with the highest marks from the judges overall! Is this a dream?!

I had no expectations at all about this and certainly didn’t think the event organiser and one of the judges would top the evening off by turning up outside my house (the event was virtual) to deliver the UK INSTRUCTOR 2020 award and gorgeous prizes.

Well done to the event organisers Community Fitness Network for pulling off an amazing virtual awards bash. Phenomenal effort as always. Congratulations to all other nominees, finalists and are champions of community fitness.

Personal massive thank you’s from me to my parents, Luke and amazing FitMixx participants for the belief and support  Thanks to everyone who voted for me. I absolutely adore what I do and to get this recognition means so much. FitMixx’s been a fabulous 10 years, roll on the next 10!!!
