Boxer Savannah Marshall is nicknamed the ‘Silent Assasin’ due to her shyness but hasn’t let that hold her back in the ring, making history by claiming Britain's first ever women's world title in the sport.

Savannah got hooked on boxing aged 12 when she joined her local club Hartlepool Headland with friends to keep fit. She won silver at her first world championships in Barbados in 2010 when still a teenager and went on to win gold at the 2014 Commonwealth Games in Glasgow.

Savannah is a full time Lottery-funded athlete training with the GB Boxing at the English Institute of Sport in Sheffield.
